Yes, definitely. Many FPS gamers as a matter of visual advantage wish to run their FPS game at the highest possible framerate, or at least as fast as their display. This usually means 144-300+ fps. And it needs to be pegged at a consistent rate (so even in the most graphically intense moments). Achieving this even on low settings and with a high end GPU is not always possible, and a high end CPU and high end RAM are required to be consistent, especially for 1440p and 4k.
