I am looking to buy a retina macbook pro and would like to be able to play games on it. The only game I play is DOTA 2 and is the GT650M good enough to play DOTA 2 comfortably (at least 60 fps) at high settings? I was planning to save some money. If 650m is not good enough should i get the retina macbook pro with 750m. Please help!!!!!
