Like I said, I personally sacrifice to reach 80 FPS, unless in 3D Vision, then it is 60 FPS. However, not everyone has the same opinion as me. Some people are perfectly happy at 40 FPS.
The only reason the topic started, was a review was done that showed AMD had microstutter issues below 60 FPS. To Fx1, the review was invalid, as they weren't playing at the "right" FPS. They way I play, at 80+ FPS, is also wrong in Fx1's opinion, because it is not at 60 FPS with v-sync on. (but he doesn't recognize it as an opinion. He called it a scientific fact earlier).
