Okay, ive done some googling and i cant really find much... my thinkpad t410 can display at 1440 x 900 at 50hz and at the same resolution 60hz and im just wondering will i get a perfomance increase from using 50hz over 60hz?? currently using 60hz and for some reason in the past monthmy computer has slowed down a lot so im just trying to improve where i can! thanks in advance
