Hello there folks, i'm still debating o which one to buy, but i'd like to wait and read the reviews of new imac's too before pulling the trigger. I know that there are 2 versions of GT650M that are installed in the non retina macbook pro's. One has 512 MB and the second one has 1GB of ram. Now i know that retina's one has higher clock rates than the cMBP. So I wonder if people who also do run windows on their machines could install 3D Mark 11 or vantage, run a few tests and post the results in this thread. I'd like to know how much crippled the non retina versions are compared to their faster brother or sister... So post results of non retina and retina GT650m here. Thanks in advance!
