I do see huge difference playing quake at 24 fps to 60 fps, you should tryThe human ability to perceive the differences in frame rates are minimal. Super high fame rates/refresh rates in games and video cards are just to fool consumers into buying new gear. They blew past the threshhold years ago. I used to have a friend that spent a fortune on Audio gear that equalized sound well above and below human hearing. If you can't hear it or see it than you were fooled into spendin g money. Granted, NTSC and PAL are pitiful signals. The quality of DVD's and Digital Cable have more than made up for that limitation, though.
