Erm, well the amount of fps counts towards whether your game laggs at all, and so it does matter. Admittely, you're not going to see any difference between 60 fps, and 70 fps, but it does matter. I mean, when someone asks for a system that will play say BF2 at 40-50fps, they are after a system that will not lagg (well hardly), and I consider the 60 figure the garunteed number to assure the person that the game WILL NOT lagg at all
YES DARN IT. and really who can see a difference between 60fps and 61fps? and when i run 3dmark or some games, if i go lower then 20fps i still dont see lag. and it looks just slightly off then when i get 100fps
