In today’s gaming environment, more and more people are taking the jump from consoles to the PC market looking for the pros that only PC gaming can provide. From the huge numbers of indie games, to the access to games regardless of console, the ability to mod games into whatever you like, playing games on PC tends to be the optimal way to play games. But now people are building new computers and not knowing how. Which part is the most important for your PC? Read on to find out.

Graphics Card

One of the most important parts of a gaming PC is your graphics card, or GPU. Whether you plan on playing FPS games, action-adventure games, point-and-click or RPG you need a good GPU. A GPU is what provides you with the top tier graphics that free to play games provide, by being a card that focuses all of its power on rendering and simulating whatever the game has to show. The more powerful the graphics card, the better your games will look, and in today's gaming world, some older cards won’t even be able to run the newest games. Therefore, if you want the best gaming PC, you need to have the best GPU.

Central Processing Unit

The central processing unit (CPU) is the most important part of any computer, whether it’s for gaming or for regular work. A CPU is like the brain of your computer, it’s what does all of the calculations to keep everything working as it should be, so in many ways it is the most important part of your computer as without it you wouldn’t have a working computer. On top of keeping the computer running, some CPUs come with onboard graphics that, while not as good as a GPU, can still run some decent graphics for small games. It’s important to remember that a CPU gets very, very hot, so if you are getting a powerful CPU you need to match that with a powerful CPU cooler.

Random Access Memory

Random access memory, or RAM, is another necessary part of your computer. The RAM, explained in a very simple way, is what moves data from your storage drives to your graphics card and CPU and back again. The more RAM you have and the faster it is, the faster your computer will process things. Having enough RAM is vital to your computer, especially as most games these days need at least eight gigabytes in order to run properly.


Though these three components are the most important in your computer, there are still a number of parts that must be taken into consideration, which contribute to the overall performance. Storage, for example, is vital, as there’s no way you can run a game if you can’t store it. Cooling is just as important, as computers can run very hot which damages parts if they are hot for too long. Finally, as many gamers will attest to, having LEDs on your components is one of the most important things you can have, as they make your computer look fantastic.
