The 3 Core Components You Need To Consider When Buying A Desktop Computer

By Jonas FitzGerald

When buying a computer, it’s important to learn a few essential things about them, as not only is it easy to be fooled by high numbers, but at the same time, you’re not being made aware of the numbers that really matter. Following this guide to buying desktop computers – best computers to buy will be made that little more apparent.

Three Main Attributes

Pretty much all personal computers follow the same rules and as such you can determine whether a computer is suited to your needs or not.

The central processing unit (CPU) is the source of most of the computer’s perceived ‘speed’. Generally, the faster the listed megahertz (MHz) or gigahertz (GHz), then the faster it will process programs. If you wish to run multiple programs with maximum performance, then a multiple core processor would be preferable, as it allows the simultaneous use of several programs at once without loss of performance. Some programs even utilize multiple cores to run faster.

For gaming, the main focus should be on the graphics card. This will deal with anything graphically-intensive and offer significant increases if it is a quality card. For this, you will want to look to either NVIDIA or AMD/ATI for a card as they are the leading competitors. The two main specs of a graphics card are core clock, and memory amount. The core clock determines how fast the graphics card is and is the most important marker of a graphics card. The memory amount will determine how often the card needs to load things like textures into it, which may cause stuttering if it needs to swap continuously.

RAM and the hard disk are two variants of memory with vastly different purposes. The hard disk is used for preserving information over a long period of time and the size you’ll need is dependent on what you need it for. A person who wishes to install dozens of games or save videos will likely need a large hard drive going up to 500 gigabytes (GB), whereas someone who wishes to save music and text files might never use even a 100GB. RAM, however, is used by everyone as it is used as a temporary memory for the CPU to keep information on hand for when it needs it. The faster and larger it is, the faster programs will load and the more you can run, provided it’s coupled with a decent CPU.

You can get all the information and details you require, to find the best computers to buy! When you want to learn the advantages and benefits of computers, you will find them easy and fast at today!
