Yeah, it is true that this macbook will not perform much better than my previous one. Excluding games. I get 50-90 FPS is counter-strike source, settings on high, native resolution. Excellent, better than I expected. My previous macbook got around 13 FPS.
It is also true that I won't be using it for gaming very often. It was however good fun to bring it over to a friends house for some CS and Left 4 Dead.
I won't bother gaming on it at home.
Not much point when my desktop PC gets 200-300 FPS at 1920x1200 w/ 8xAA 16xAF
