I was set for a base 15" before this launch, now i orderd the high 15" with a high res screen. But im thinking back to the 2010 15" model. There you had a gt 330m 256mb version, and a optional gt 330m 512 mb version. Not a huge difference in terms of peformance Why do you think apple released so different gpus for the 2011 15". The difference between the two gpus is kinda huge. It just seems like a weird choice to me.
