Graphics cards (aka GPU's) are mainly used for gaming, or rendering. Your GPU will be the #1 factor in how high your FPS (frames per second) is on any game. The higher the FPS, the smoother your games will run. This is also true for programs that need to 'render'. If you do a lot of video editing, your graphics card will affect how fast you can render your video. Our guides will show you how to pick the right graphics card to compliment your PC build.
