My apologies if this topic was brought up before, I'm attending university soon so I'll need a notebook. This will be my primary and only laptop, and hopefully it could be staying with me in 3 years of university. The MBA has an excellent battery life and is very portable, thus easy to carry around in campus, but I don't know if 1440x900 will suffice in the long term. I do some gaming in my pastime, so I expect my notebook to be able to deliver 30-40 fps running on med settings (Dota 2, Skyrim, Diablo 3, Starcraft 2 etc.) I've read that the rMBP will come with Iris Pro 5200 on top of the obviously superior screen, but I'll have to put an extra $400 for that. Also, which upgrades will I need? 256 SSD? core i7? 8GB RAM? I don't run virtualisation; all I do will be typing for assignments, watching videos, storing music & photos and do some gaming.
