Hello everyone. I have a dilemma about choice model of MacBook Pro. The maximum amount I can spend is approx. £600. I'm thinking about two specific models, namely - MacBook Pro 8.2 - i7-2635QM / 4GB RAM / 500GB HDD / 6490M / 15" or MacBook Pro 9.1 - i5-3210M / 4GB RAM / 500GB HDD / 13". Mac will be used at home of course, but also in college - programming (java applications on OS X + Windows and other cross-platform applications) + design in Photoshop (design web pages etc.). I don't hide that I prefer the 2011 version with the 15" "screen and i7 processor, but if the gap between them will be substantial, I'm willing to give up about size of the screen. The only thing that worries me is information which I read about these models. Namely, apparently there are some problems with GPU. Is it applies to a large percentage of these models? Maybe I shouldn't be worried about this because the shop from which I'm going to buy a MacBook provides 12 months guarantee to every Mac but I want to be sure. I just want to save my time. That's why I need advice - whether it is better to choose version with an older SB i7 processor (4 cores, 8 threads) and 15" screen or newer versions with i5 (2 cores, 4 threads) and 13" screen. I will be very grateful for any suggestions. Regards.
