Going to start my 2nd year of College this September and am planning to sell my 24" iMac to purchase a new 15" MBP. I'm stuck between the 2.53GHz model and the 2.66GHz. Only because the 2.53GHz model only has the 9400M while the 2.66GHz has the 9400M and the 9600M GT. While I do play some games on my Mac and wouldn't mind the extra power, I play most of my games on my PS3 and likely could live with a 9400M. My biggest concern is if the 9600M GT plays 1080p video any better then the 9400M? If anyone could tell me how the two are on 1080p video that would be much appreciated.
