Also, remember that if you buy a cheap LCD/TFT monitor than you have the risk of getting dead pixels. There is nothing more annoying, than having one of them, as there is a black dot on the screen.
Anything below 16ms will be fine (just). If you get 8ms than it will be even better. If you get anything above 16ms, than you will get ghosting.
CRT's are the best for gaming though.
BTW, Crazed_Climber, your sig is way too big.
