Do you need that much FPS? Can anyone really tell much above 30fps? That used to be my baseline for knowing when I could finish tweaking the settings and start playing.
Absolutely. There is a clear difference between 30 and 60 fps when playing computer games.
Anything above 60 is gravy, but getting a game to stay at 60 is what you want, since it tends to be the refresh rate of the screen you're playing on.
