Gaming is an expensive hobby, and enthusiasts always need to choose between upgrades. They’re searching to find the best value for their money, which is why metrics like “FPS per dollar” and “cost per frame” are often referenced. While this kind of logic applies to CPU or GPU upgrades in an enthusiast gaming rig, it falls short of quantifying the importance of peripherals in gaming. Even a no-compromises gaming PC build can be limited by mediocre peripherals, such as a headset, keyboard, mouse, or monitor.
