Desktop PCs are the ideal form of a computer if portability and mobility are not important to you. The conventional desktop has the best price-to-performance ratio and is also easily upgradeable and repaired. There are also other forms of desktop PCs such as mini PCs and All-in-One PCs, offering different products to different preferences.

Before you buy a new desktop computer, it's important to understand how factors such as the CPU and RAM affect system performance. You must also take into account any peripherals you'll need, such as connector parts and optical drives. Here's an overview of factors to consider before you shop for a desktop computer.
Evaluate Your Needs
Ideal computer specifications are determined by your specific use case. For example, how fast your PC needs to be, depends on what you plan to do with it. For a gaming PC, a fast processor and sufficient RAM, as well as a powerful graphics card, prove important. If you plan to use your computer for browsing the web and simple productivity tasks, such as word processing, then a lower-tier budget desktop should suffice.
While there are many different desktop processors or CPUs, most come from just two manufacturers: AMD and Intel. Intel processors generally offer better performance, but they are more expensive than AMD processors. However, the main difference between processors relates to the number of cores they offer and their relative speed.
Most manufacturers present a performance rating system for their desktop PCs, but comparing across brands isn't always easy. Your best bet is to look for PCs in your price range and then research the processors to make sure they are powerful enough for your needs.
Memory, or RAM, plays a big role in the speed and performance of a PC. The higher the RAM, the better the performance. Experts recommend at least 8 gigabytes of memory, but 16GB offers better performance. For gaming and other power-computing uses, 16GB is the minimum you should consider.
Although DDR3 memory was the standard for a desktop computer for many years, DDR4 is now preferred. When buying memory, try to buy as few DIMMs as possible to allow for future memory upgrades.
While some desktop computers still rely on hard disk drives, most newer PCs ship with solid-state drives for storing and caching data. SSDs are preferable since they're faster, more efficient, and more durable than HDDs. There are two main elements to consider when shopping for hard drives: size and speed. A modern desktop hard drive should have at least 1TB of storage space. In terms of speed, most run at 7200 rpm, but some green or variable-speed drives consume less energy.
Optical Drives (CD/DVD/Blu-Ray)
Most desktops still come equipped with a DVD burner, but some small form factor PCs are doing away with optical drives. To watch new movies in HD, your desktop needs a Blu-ray drive. If the computer you want doesn’t have any optical drives, purchase an external CD, DVD, and Blu-ray player.
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 onboard memory. Pick a budget video card if you’re just interested in accelerating non-3D tasks. Factors to consider include performance, the amount of memory on the card, the output connectors, and the version of DirectX supported.
External Peripheral Connectors
Check how many and what types of external parts are available on the computer for use with future peripherals. There are a variety of high-speed peripheral connectors now available. It is best to get a PC with at least six USB ports. Other higher-speed connectors include eSATA and Thunderbolt, which can be especially useful for external storage. Many desktops also include SD card readers.
While there are all-in-one PCs with built-in monitors, you still need to consider the quality of the screen. Most monitors today are based on LCD technology and the only major difference between them is size and cost. Some other factors, such as colour accuracy, may be important if you plan to use the desktop for graphics work. 24-inch LCDs are the most common, thanks to their affordability and support for full 1080p high-definition video.
What is the best desktop computer for gaming?
The best gaming PCs are the most powerful tool at your disposal for both video games and productivity software. Blasting through hordes of foes at rapid frame rates and high resolutions is fun, but you can just as easily use a gaming rig for graphic design, animation or simply streaming movies and TV in beautiful 4K. While the PS5 and Xbox Series X will deliver more power than console gamers currently enjoy, they’re still no match for some of the best gaming PCs. If you want fast-loading SSDs, gorgeous ray tracing, massive quantities of RAM, 4K resolution and 60+ fps frame rate, you don’t have to wait until holiday 2020; you can have them right now. And unlike a console, you can upgrade PCs as better tech becomes available. Here are some of the best PCs you can buy:
- Alienware Aurora R10
- CyberPowerPC Gamer Extreme VR
- Dell G5 Gaming Desktop 5090
- Corsair One i160
- iBuyPower Snowblind
- Maingear F131
