6 Essential Things Must Know Before Buying A New Desktop Computer – No Buyer Ignore It

So are you looking for a new computer but not sure which device you want or need? Before buying a new desktop computer, it is important to understand how factors like CPU and RAM affect system performance.

You should also consider the peripherals you will need, such as connector ports and optical drives. Here is an overview of the factors to consider when buying a desktop PC.

What follows in this guide will help you better understand what pre-built desktop PCs can offer you, as well as the many variations of these products.

Why a desktop PC?

If you can live without the portability of a laptop or tablet, desktop PCs can provide you with more power and a different form of convenience. Compared to laptops, most pre-built PCs are more upgradeable.

Sure, you can swap hard drives, SSDs, and memory cards on some laptops, but their CPUs and graphics are often soldered, so their graphics and processing power will stay the same until your next purchase.

Depending on the manufacturer, pre-built PCs can swap most, if not all, of the components, including the graphics card, motherboard, and CPU. However, you should be sure to check its specifications every time you change components.

Another great thing about desks? You don’t need to worry about charging a battery. Just plug it into a viable outlet and you’re done.

Fortunately, since you’re going with a precompiled version instead of doing it yourself, you don’t have to worry about compatibility issues at first, or making sure your PSU can handle your components.

In the future, when you decide to upgrade, you can use Newegg’s power supply calculator to make sure your system has the correct amount of power.

Advantages of a desktop computer

Desktops are the big kids on the block. Traditional tower box, mini-tower, and horizontal ‘form factor’ models offer a spacious box with an easily accessible interior. (The form factor refers to the specification of the motherboard, which influences the size of the case.)

Even the relatively compact all-in-one models mostly offer oversized, full-power components and a large screen, albeit without the extra internal space.

Keep in mind, though, that some models looking for a slimmer, slimmer look may include portable-style components like built-in graphics (on the motherboard rather than a dedicated graphics card) and even a 2.5-inch hard drive (on instead of the standard 3.5-inch) or just a solid-state drive (SSD).

Types Of Desktop Computer

Desktop computers are divided into three main families:

  1. Tower

The traditional desktop computer has a large and spacious vertical box (which, due to its size, is usually located under the desk). While bulky, it offers unmatched versatility and the opportunity to upgrade or replace parts to extend the capabilities or life of the unit. Mini tower (vertical) and horizontal form factor models have less interior space.

  1. Compact

Also known as a small form factor (SFF) or Mini PC, these sandwich-size computers include small components as an all-in-one, but without a built-in display.

  1. All in one

If you’re looking for a general-purpose desktop with a large but compact screen, an all-in-one might be just what you need.

These stand-alone desktop computers contain all of the components plus the monitor in a single unit that looks like a desktop monitor. The computer itself is usually integrated behind the screen.

Although they lack the expandability of a traditional tower box unit, they provide a stylish alternative that can even save space and can be a multimedia focal point for the whole family.

If you skip a slim all-in-one for a modular PC (tower or compact models), there are a few advantages:

  • Connections – In a tower model, the extra space generally means you’ll find a wider range of connection ports and more of them.
  • Cooling: Bigger fans and more space mean better cooling, so you can use high-end components like faster processors and graphics cards.
  • Space: In comparison to a laptop or an all in one model, the traditional desktop case provides much more space inside which leaves more room for additional drives or a second graphics card.
  • Upgrades: In order to upgrade or replace parts, traditional desktop tower case offers much more flexibility so your desktop PC can last much longer with some well-chosen upgrades.
  • Versatility: You don’t have to buy a finished box on the shelf. You can customize a desktop PC to suit your needs and budget, whether you build your own or pay a professional to do it all.
  • Cost: A bigger case can actually mean big savings: it costs more to do small things.

How to choose the right desktop

Regardless of the family of desktop computers you choose, choosing the model to suit your needs requires a little planning. Consider the categories fit into:

  • Basic level

A cheaper computer created to cover all basic activities, such as surfing the Internet, writing emails, and occasionally using office productivity software.

  • Middle range

A complete service for browsing the web, email, office programs, and other general-purpose software and casual games. This type is generally aimed at families, students, and entrepreneurs.

Mid-range computers can run most programs and games, but they may struggle with high-end programs such as video editing and high-end games that require very fast graphics processing.

  • High-end

The sky is the limit with performance and cost. There’s plenty of scopes available in this category, depending on the type of processor, graphics card, and storage you choose.

6 Essential Things Must Know Before Buying A New Desktop Computer

However, don’t just consider your current needs. Look to buy a system that will still serve you well for the next three years or so. Check which parts can be updated later; For example, can key components like the processor, graphics card, and hard drive be easily replaced by better ones at a later date?

  1. Evaluate your needs

The specifications of a computer (“specifications”) are determined by your needs. For example, how fast your PC should depend on what you plan to do with it.

For a gaming PC, you’ll want a fast processor and enough RAM, as well as a powerful graphics card. If you plan to use your computer to surf the web and perform simple productivity tasks like word processing, then a budget desk should sufficient.

Take a moment to evaluate how you use your computer and determine the requirements required by any specialized software.

The first thing that most of us are limited to is budget, so this is the first thing you should consider. We always want the best, but we must base ourselves on what we can afford. So get a quote and stick to it.

  1. Desktop processors (CPUs)

Most manufacturers have a performance rating system for their desktop PCs, but comparing brands is not always easy.

Your best bet is to search for PCs in your price range and then research the processors to make sure they’re powerful enough for your needs.

This is the most important factor when choosing a computer nowadays and there are many factors in choosing the processor, the main thing is that in my opinion Intel is making the best chips right now and its core 2 duo range is the best, so choose one in This family and you will be fine.

While there are many different desktop or CPU processors, most come from just two manufacturers: AMD and Intel. Intel processors generally offer better performance but are more expensive than AMD processors. However, the main difference between processors is related to the number of cores they have and their relative speed.

CPU is the brain of your computer. The number of cores, the processing power, and the price range is a good indicator of the overall level of power on offer.

Be careful when comparing the Intel CPU family with those of AMD, its main competitor, as the quoted speed figures are not directly comparable. Similarly, with the subfamilies of each brand: Intel Core i3, i5, and i7 and the latest M series processors have increasing performance, even with the same figure quoted in GHz.

If you want a fast computer that starts programs in an instant, complete tasks as soon as they start, and don’t make it wait, then you want the most powerful processor available, and who doesn’t? You just have to know what you are seeing when you see the details of a processor.

  • Basic: The short and simple of the processors is in the number of cores and the speed (labeled in GHz or Gigahertz) of the processor. The chip speed will tell you how much data it can process in how long, so the higher the number, the better. The number of cores works as a multiplier, as the processor is actually a stack of cores running at the stated speed (for example, a single-core 2 GHz processor is much slower than a 2 GHz processor quad-core).
  • Multiple cores can also help with multitasking, as each can be working on different tasks. If you don’t use many programs at the same time, you can be content with one or two cores and you don’t need to shell out the extra money to get some more. Be sure to ask how many cores are on the chip and what is the clock speed. Two computers might say they have an Intel i5 chip, but the number of models that fall into the group is many, and their speeds and core counts can be leagues apart.
  • Advanced: If you want to get into really sharp processor details, check out the benchmark tests at CPU Benchmark. You can compare several different CPUs to see if you’re getting the best, and even see if you’re getting the best for your money. Also, check out the L1, L2, and L3 cache sizes – these are the closest and fastest memory spaces for the CPU, and the bigger the better. You can also see how many threads the kernel has; again, the more the better.
  1. RAM

Random-access memory (also known as RAM or desktop memory) helps speed up your computing experience by storing system information for monitoring and on-demand functions.

The higher the RAM, the better the performance. For gaming and other uses of power computing, 16GB is the minimum you should consider.

As software, like games and applications, gets more advanced, larger desktop memory is needed to run your PC efficiently. At the time of writing, you will need at least 8GB of memory to run video editing software like Adobe Premiere.

The latest games currently range from a minimum of 2GB-8GB of RAM, but the safest current bet is to go with 8GB. Of course, if you are just trying to run Microsoft Office programs, 2GB will work fine.

Essentially, the more rams you have, the more browsers and applications you can open. 4Gb is the most basic today. 8GB is the sweet spot for most people.

If you are a gamer, photo or video editor, or planning to do CAD / CAM work, be sure to get 64-bit Windows Vista as your operating system. For most manufacturers’ pre-built desktop PCs, desktop memory is one of the components that can be easily changed in the future. But you must be careful to maintain both type and speed.

RAM is basically a small, superfast form of memory (like L1, L2, or L3 cache, but bigger and slower).

Basic: Today, most RAM is measured in gigabytes, and, as is often the case, the more the better. By having more RAM, your computer can have more data on hand, instead of having to search the slowest hard drive for the information it needs.

Of course, because the RAM is smaller, there is only a lot of space for the data. So having more RAM is useful if you want to keep multiple tasks at the same time and be able to jump between them relatively quickly.

Advanced: There is, of course, a little more RAM than just the size of it. If you go through the details of RAM on a computer and see that it is DDR2-800, you may have a quick idea that this is faster memory than one labeled DDR2-400, since that last number means how many millions of data transfers RAM can do every second.

However, that speed is limited to the speed of your computer’s motherboard, so if you are buying RAM separately from your computer, calculate the speed of your motherboard and don’t buy RAM that is faster as it probably. It will cost you more for no reason and don’t buy slower RAM as it will force your motherboard to run at a slower speed.

A final number you can see is in the module name, where you can see something like PC3-8500, which indicates that the memory can transfer around 8,500 MB per second.

  1. Hard drives

Every computer needs data storage, and while that is something that RAM does, most will go to your hard drive. While some desktop computers still rely on traditional hard disk drives (HDDs), most newer PCs come with solid-state drives (SSDs) to store and cache data.

SSDs are preferable as they are faster, more efficient, and more durable than HDDs. Lack of RAM will slow down your computer when multitasking or laborious like image processing. Look for a minimum of 4 GB (gigabytes), even on a budget system; ideally, target 8GB for most general-purpose PCs.

There are two main elements to consider when buying hard drives: size and speed. A modern desktop hard drive must have at least 1TB of storage space.

In terms of speed, most run at 7200 ROM, but there are a few optical drives (CD / DVD / Blu-Ray) Most desktop computers still come equipped with a DVD burner, but some small form factor PCs are eliminating optical drives.

If you want to watch new HD movies, your desktop will need a Blu-ray drive. If the computer you want doesn’t have optical drives, you can always buy an external CD, DVDs, and Blu-ray players.

This is the next piece that you should tackle. Today’s computers generally come with 250GB and 750GB of hard drive space. As more people store their information online in cloud storage, you may want to rethink purchasing a large space on your hard drive.

Where to get free cloud storage;

Google provides the first 15 GB of a free monthly fee of $ 1.99 for 100 GB and $ 9.99 for 1 terabyte.

  • Mega provides 50GB for free
  • pCloud provides 10GB free
  • Media Fire provides 10GB
  • Dropbox provides 2GB

Don’t underestimate how much you’ll need! Make sure you have enough space on your hard drive for all of your current files and programs, as well as the rapidly growing collection of videos and music that most people now tend to accumulate.

Find a 1TB HD as a starting point, but double it if you can. Hard drives can be up to 3–4TB. Desktop tower models make it easy to add a relatively inexpensive additional internal hard drive in the future, or perhaps a super-fast Solid State Drive (SSD) for additional performance.

Primary storage for prebuilt desktop PCs boils down to internal hard drives (HDDs) and the latest internal solid-state drives (SSD) format. Following the standards that determine product price and efficiency, the current way that most users use desktop PC storage is as follows:-

  • Use a high-capacity HDD to store your large collection of multimedia files, such as movies, music, images, important documents, etc.
  • Use a small to medium-size SSD to house your operating system (OS) and essential programs.

This common and useful configuration involves both an SSD and an HDD on a single system, although HDD-only or SSD-only options are also available, depending on your needs.

The amount of storage you want for your SSD is between 120GB and 240GB. This gives you plenty of space to store your key operating system files, as well as ample space to store your other most-used files and / or applications. Because hard drives are becoming increasingly affordable every day, the standard size you will be looking for should be between 500GB-2TB.

Usually, there are a few different options to consider when looking for a hard drive, but it really comes down to how you plan to use your computer.

Basic: If you plan on having only your computer and no peripherals, you can go for the largest hard drive you can (measured in gigabytes or terabytes for extra-large drives).

If you don’t plan to have a lot of applications on your computer, and you’re not going to store media on it, you can go for a smaller hard drive and save some money. If you can handle a small hard drive but want it to be faster and have the cash, consider opting for a solid-state drive or flash hard drive.

Advanced: The size of your unit is one thing. If it is a disk drive, the spin speed is different. Naturally, the faster your hard drive spins, the faster you can get information from it.

So between a 5400 rpm drive and a 7200 rpm drive, the latter would be faster.

If you can manage to have only a few larger programs installed on your computer at a time, and plan to keep everything else stored on an external device, you can probably get a quick device with a solid-state drive to keep the computer up at all times, and still manage to transmit high-quality media through a USB connection; some applications can even be run from an external hard drive. You’ll also want to pay attention to the data transfer bandwidth.

  1. Video / graphic cards

If you don’t play PC games with 3D graphics, then you don’t have to worry about a dedicated graphics card. Gamers should consider a DirectX 11 card with at least 2GB of built-in memory.

There are also inexpensive video cards if you’re only interested in speeding up non-3D tasks. Factors that should be considered comprises of performance, the amount of memory on the card, the output connectors, and the version of Direct X supported.

Now all computers come with some form of integrated graphics. But, you can go with something a little better possibly from NVIDIA or AMD. They improve the resolution of your computer. NVidia is good for Adobe programs whereas AMD cards are good for mining.

Entry-level desktops may have the graphics processor built into the motherboard called integrated graphics, rather than a separate (dedicated) graphics card.

While built-in graphics is generally suitable for most everyday tasks, high-end gaming, and other graphics-intensive programs will greatly benefit from a dedicated graphics card (which can also be upgraded in the future). Certain high-end programs may require a dedicated graphics card to run.

Lately, computer manufacturers have been labeling labels on their computers to boast of the AMD or NVIDIA graphics cards they have included in their machines. Unfortunately, that means a thousand different things, and it’s quite difficult to know what.

Basic: If you just want to know if the card on the computer on the left is better than the one on the computer on the right, you can do a quick search on the PassMark site for the graphics components of each. Some buzzwords to keep in mind are “integrated” and “dedicated”.

The first is integrated into the computer’s processor and depends on the computer’s memory; this is typically a lower-performance graphics component. A dedicated graphics card will include its own processor and memory and will tend to be higher performance, although a very old card might not be the best modern integrated graphics.

Advanced: If you are analyzing the details of the graphics processors, you will have to think of them as your own pair of processors and RAM. This is another case of more, better.

A faster RAM and higher capacity on the graphics card will allow you to handle a higher graphics load and do it faster. This will allow for better and smoother images. The speed of the card’s processor will be equally important and can be seen in much the same way as a computer’s processor.

  1. External peripheral connectors

Check how many and what type of external ports are available on the computer for use with future peripherals. There is the availability of varieties of high-speed peripheral connectors in this present time. It is better to have a PC with at least six USB ports.

Many desktop computers also include SD card readers. Your computer’s peripherals will be quite specific to your needs, so you’ll need to think about whether you will need them and how many you want.

You may want ten USB ports but don’t worry about having a DVD drive. On the other hand, you can do everything online and you just want the fewest holes in your machine as possible for the soda to spill out and drain the circuits.

USB: If you plan to transfer a large amount of data, make sure you have a fast USB port or a fast wireless network. An alternative for some important external ones (like CD drives and hard drives) is to get a computer with an eSATA port, which will allow you to connect those peripherals on the go with high data transfer rates.

Fortunately, there is a standard that most computer peripherals choose to use, and it can be for anything from mice and keyboards to hard drives and monitors;  you can even connect a guitar via USB if you’ve found the right cord.

A modern version of USB, called USB 3.0, is faster than its predecessors, but there’s an even newer version of USB, called USB Type-C, It offers gigabits of bandwidth. While USB Type-C will eventually become the only technology you’ll use to connect all of your devices.

HDMI: If you are going to use your desktop for entertainment, you probably want an HDMI output. This will allow you to connect it to most modern televisions for a high-quality visual display, and will also output the audio output if you plan to use the television for sound.

SD slot: If you work a lot with photography, an SD slot can be a handy way to bring files from your camera to your computer. For computers with small hard drives, an SD card can also function as a small addition to the general memory of the computer. For slightly smarter users, SD cards can even be used to speed up the system.

Audio input/output; If you’re using wired headphones or headphones with microphones, these 8mm jacks on the front and/or rear of your desktop PC are what you need to connect.

Typically the front I / O panel has these 8mm jacks differentiated by a microphone icon (audio input/microphone input) and headphone icon (audio output/headphone jack)

Video (VGA, DVI, HDMI, and DP); On the back of your desktop PC case, you’ll find the standard video connections: VGA, DVI, HDMI, and DisplayPort (DP).

As for which is better … well, it’s not as easy as saying “this is better than the others”. VGA is indeed older and may have trouble converting your analog signal to digital signal, but DVI, HDMI, and DisplayPort usually boil down to which ports are on the back or side panel of your output source which is TV or monitor.

For gaming use, both HDMI and DisplayPort have their advantages, and the right choice for you depends on your graphics card, monitor, and other aspects of your setup.

Ethernet / RJ45; Using the RJ45 port (also known as Ethernet) is the fastest and most reliable way to connect to the Internet. As long as you have a working router or extender and you have an Ethernet port, all you have to do is connect both ends of an Ethernet cable from the network device to the back of your desktop PC.

However, it should be noted that not all Ethernet cables are built in the same way. Cable Internet speed may depend on the category (eg Cat 5 versus Cat 6), as well as the physical length of your cable (shorter = faster).

Desktop monitors

While there are all-in-one PCs with built-in monitors, you still need to consider the quality of the display. All of today’s monitors are based on LCD technology, and the only big difference between them is size and cost.

Some other factors, such as color accuracy, may be important if you plan to use the desktop for graphic work. 24-inch LCD screens are the most common, thanks to their affordability and support for 1080p high-definition video.

Larger displays, like 27-inch LCD displays and 4K PC displays, are also falling in price. Green or variable speed drives in fact consume less energy. Some high-performance 10,000-rpm drives are available, such as M.2 and SATA Express.

Wi-Fi: If you plan to connect to many networks in many places and want to do it wirelessly, it is probably better that you get a built-in Wi-Fi receiver instead of working with some kind of external Wi-Fi.

Wi-Fi devises If you’re running a desktop computer, you can probably run an Ethernet cable straight to the computer without constantly being bothered by the need for a cable to connect to the Internet.

Bluetooth: Just like Wi-Fi, you can get a built-in Bluetooth receiver with your computer, and that can be a smart move if you want to be a true wireless warrior.

Whether it’s for sending audio to headphones or a 7.1-channel surround sound setup that will keep your neighbors alert, Bluetooth is a handy way to make those connections easy and tangle-free. It may be worth it for these types of uses, otherwise, you can probably save a few bucks by not looking for it.

Things to keep in mind When buying Computer

  • When buying a new computer, as with any expensive purchase, the most important thing to do is to be very patient. Technology is evolving rapidly, and if you bought a new computer today, you may not have noticed that a new one will launch tomorrow, and it probably would have cost the same as the one you just bought or made it less expensive. You could go into a logical loop that has you waiting indefinitely, but choosing the best time to jump is key.
  • Check product update cycles.
  • It can also be helpful to be friendly with the computer manufacturer’s website, as they often allow you to customize a computer platform with the components you want. On top of everything, you’re much more likely to find an amazing sale if you shop regularly for a good period of time rather than just spending most of the day choosing and buying right there. Also, don’t be afraid to spend a few more bucks to push your computer’s specs; If you make the cheapest purchase, you may want to buy another new computer much sooner than you would otherwise.
  • One last piece of information: Go ahead and ask a salesperson to give you a deal. They may not lower the price of the computer, but if you are going to need a mouse, keyboard, monitor, or any other device that goes with your computer, see if they will reduce the sales tax or give you another discount for buying the items together. You will often be pleasantly surprised.
