As with many things in the gaming world, the answer to this question depends on your preferences. 1440p and 4K look crisper than 1080p; this much is not debatable. That said, your GPU is not capable of generating the same frames per second at 4K as it is at 1080p because there are only so many resources to go around.This is why competitive gamers still tend to prioritize 1080p over higher resolutions: it gives them smoother gameplay, faster reactions, and better results. Most of us aren’t competitive gamers, though, so there’s no need to use lower resolution for a competitive advantage. If you’re into single-player and casual games, there’s no problem with splurging for a crisper picture.
