Hi Guys, really finding it difficult to decide on making the final plunge to do away with my Windows Machines and going totally mac. Looking at 15 inch MBP or RMBP. What I would like to know (cant find the answers). What is the GPU performance difference between the MBP and RMBP. I play Diablo 3 and BF3. I can only assume that the additional pixels that need to be drawn by the GPU regardless of resolution would cause lower FPS on the retina display. I know D3 plays well on RMBP but very little info on BF3. I would really like to know how well these games perform on a 15 MBP? Can anyone help?
