Hey all, I'm needing to upgrade my computer very soon and would love to get a Macbook pro. However, i'm deciding if I should go for a late 2011 model which has the 1gb amd 6770m or get the base non retina model which has the 512 mb gt 650m. It's either between those two as the base non retina display model, which is the more expensive one, is my spending limit. I do plan on gaming on this system, when I'm not working, so getting medium to high settings are fine for me. Occasionally I will use an external monitor for the system so I will playing games not just at the normal 1440x900 resolution. Any ideas which one I should get?
