The interesting thing about framerate, is it has nothing to do with how fast the machine responds.
You don't see the results of your actions until the next frame, period. "How fast the machine responds" is almost completely irrelevant if you can't see the response onscreen.
Back in the days of 16 bit color there were people who said that the human eye could not distinguish any more colors than that and that anything above 16 bit color was a waste. Same with 24 bit color. Same with AV cables, and S-VHS cables. Same with 24 / 30 / 60 fps.
The fact is the human eye can very easily distinguish between 30 and 60 fps, and that 24 fps is only the standard for movies because animating things at 24 fps is cheaper than animating them at 30 while still looking passable.
Some people could probably tell the difference between 40 and 60, and some people between 50 or 60.
If you see them side by side you can tell unless you have severe vision problems.
