Hi, I'm not a big gamer but want to play Diablo 3 when it comes out. I have two Mac laptops, and wondering which one will be a better machine for it. The two options are: MacbookPro 15" (2009 Model) 2.40ghz Intel Core 2 Duo 2 GB Ram Dual Nvidia GeForce 9400M/9600M GT (256mb) Currently running OSX 10.5.8 or Macbook Air 13" (late 2010 model) 1.86ghz Intel Core 2 Duo 2GB Ram Nvidia GeForce 320M (256mb) Currently running OSX 10.7.3 Which of these machines is better suited for a game like Diablo 3? Both meet minimum requirements, but not by much. If it's the Macbook Pro, I'd have to upgrade to OSX 10.7, which I wouldn't otherwise bother to do. Any thoughts on which machine is better, or what sort of performance to expect from either of them? And will adding RAM make much difference in either case? Any comments appreciated, thanks!
