It really depends on what and how you play. If reaction time is important then you’ll feel more than see the difference in refresh rates. If none of your games require sub second reaction time accuracy, then it’s much more of a nice to have luxury than a game changer.

Also, frametime pacing matters a lot. If your system very consistently puts out 30 fps, you’ll have more accurate keypresses than if you normally get 50 and it gets hung on a few frames and it dips to 30fps. Your nervous system adapts pretty well to consistent delay, but it’s much more difficult to compensate for delay that varies a lot.

I don’t really play first person shooters so resolution matters more to me than framerate.
