Most Important Parts of Gaming PC

It’s worthy of learning about each hardware parts in a computer does and how it can affect your game. Why do we need to learn? Because if you want to play many games and you haven’t got the best computer, likely that you might face performance issues (like lag, low frame rates, or slow load times) at some point.

Understanding what each hardware part in your computer is doing will help you to recognize which part is the leading cause of the issues, and then you can look at upgrading or fixing that specific component. You don’t always need to purchase an entirely new PC if your existing one isn’t running games well sometimes, you need to upgrade a single component, and that can remove bottlenecks and can save your money as well.

Here’s a list of the most important parts of gaming PC, and what each one does when you play a computer game.

List Of Most Important Parts Of Gaming PC


A Central Processing Unit also called the central Processor, is one of the essential components of the PC. CPU typically handles actual game play when you are playing games. It takes in put instructions from your mouse and keyboard, running the game, loading maps and background images,and processing inside the game. CPU does calculations and then passes on to the graphics card to finally display these handled items.


Your computer’s memory, also called RAM, holds short-term information or details. This information is continuously being accessed used by the CPU. It is like a temporary storage spot where you would put the things to store for a short time. CPU can faster access the information containing in the RAM as compared to the hard drive.

Graphics Card

A graphics card is considered to be an essential part of a gaming PC. Anything displayed to the screen or Monitor comes due to the graphics card. It handles the processing and rendering of images received from your central processing unit (CPU) and displays it on your screen. Many graphics cards have features to handle particular graphical views of game play. Some of the features are image rotation, delicate textures, anti-aliasing. It helps the CPU free from these specific operations, which increases the processing time and is handled by the graphics card.


The hard drive is the storage place where many of our games are store. CPU cannot stores much data. It takes the data or information from storage and then makes it possible to display. We can retain data through storage even permanently or not.


The motherboard connects all the main components together and makes the electrical links between the main components of the PC.

The speed can be affected if it passes the information serially (means moving the data one by one through a single wire) instead of passing it in a parallel manner (information can be passed through multiple wires at a time).

For the excellent motherboard, it is necessary to be optimized so that speed could not be limited to transfer information (typically, you will be limited by components like your CPU, storage drives, or graphics card long before your motherboard).

Power Supply

Power Supply does not directly affect the game play. However, inadequate power supply can affect gaming. For functioning well, your system needs to have a reliable power supply.

Optical Drive

For some gamers, optical drivers(commonly known as CD drive) are required. CD is rarely used nowadays for installing games, but sometimes you will need to fix it through a CD disc. The actual game play is not affected by the disc if you are only using it for installation purposes because it can be removed after installation. Your Optical drive should be faster because if you are playing and at the same time you have inserted the disc, it would cause the system to be slower.

Optical drives are optional, not necessary because nowadays, people are not using it commonly, and the industry is moving towards downloading. So, most people download games rather than install it using a disc.


Your computer should have adequate cooling because heating is one the enemy of computer hardware. For gaming, the system needs to be cooled because if it is hot, it can cause to slow down the speeds of components because they automatically start wind back their speeds to reduce overheating. For cooling, you should have proper fans and ventilation.

Display Monitor

Your display can affect how well your PC can handle games. Screen resolution (number of display pixels – e.g. 1920 x 1080) is one of the most critical factors of the graphics display. By using high resolution for playing games, it can overload the graphics card. You can adjust your screen resolution according to your screen.
