I purchased, or thought I purchased, a 15 inch unibody MacBook Pro, the new one, about 2 days ago. It was the 2.53 GHz one with the 9400M and NO 9600M GT. What I was sent home with was an older 2.4 GHz 15 inch unibody MBP with NO SD card slot, but it has the 9400M and 9600M GT with 256 dedicated. Is the one I got faster than the one I purchased? In other words, is the 2.53 GHz enough to make up for not having the 9600M GT as far as graphical performance? PS - I bought it for 1600 with the 100 off college discount, and they said I can return it within 30 days to switch it out.
