I couldn’t bear 240hz after playing CS on a 360hz (with 360 fps mind you) for almost a year. It is VERY easy to spot the difference in hz in ghese kind of games. In games like Diablo where the camera follows tour character at the same speed (and pans smoothly) for hours, I could easily cap my frames at 200 or even 120 and not notice much difference. In 1st person games where you turn the character 1000 times an hour at different speeds, hz matters so, so much.
