The ATI 6750 is alot faster.

The 6490m is not on par with the 330m btw.
 
The 6750 is significantly faster, even faster than the "5670" in the iMacs. It will be a decently competent gaming chip if that were you plan.

So then what is it??? Better? Worse?
 
there are NO exterior changes right? besides the thunderkrap? At least i can get a zagg and case right away..

I like the gpu change if its that much better.. my late 09 had the 9600gt 512mb and id imagine this thing crushes it.
 
I would guess the 6750M to be 40-50% faster for games. The i7-2720qm will hgelp in that regard too in games that exploit extra cores like F1 2010 and Assassin's Creed 2.
