As it's been said many many times before the human eye can't distinguish anywhere near that speed. With a 144 hz screen and a monster Computer pushing it I honestly think I can see a difference between 60 hz and 75 Hz (manually capping frames) from 75-100 hz I think maybe I can tell the slightest difference, but I honestly think the fact all 144hz monitors are very good quality has more to do with it than the actual hz. Anywhere from 90+ is all exactly the same. I know people swear up and down it's soooomuch better. Perhaps, but I think it's more likely the quality of the monitor, or a placebo effect.
