Now I know this is a very nooby question, but in my 6600gt menu there is Screen Refresh option, from 60 to 75 hertz. Should I put this as high up as it can go?
Although, some games like Doom 3 were capped at 60FPS, so setting higher refresh wouldn't actually do anything noticable to the game play... I have a CRT still rather than TFT and hitting 60FPS with my rig is very very hard!
