My Atari could switch between 50 and 60 Hz because of US/EU TV standards. The difference was very noticable especially if you didn't look directly on the screen. The flicker is very hard on the eyes at 50 Hz and much better already on 60 Hz. Later I had a CRT screen that could be run at 75 Hz with some tweaking and that was very nice. Next screen I buy will be something higher but right now I'm back at 60 Hz with an IPS screen and I'm not totally happy with the flickering. Haven't tried overclocking yet, thought the flatscreens were locked to a certain Hz.
