Hi there, First of all let me apologise if this topic has already been answered. I spent some time searching through "gaming on Macs" and didn't really feel like I got the answer I needed. I currently have a 2011 13in MBP, which I am thinking of replacing. For the work that I do, the specs on an Air more than suffices. However, I do like playing the occasional game and I have heard that the Air may suffer a little. I haven't seen a shootout between the two so I can't really judge if this information applies to me. On the one hand, I don't play a lot of action or FPS games that seem to require higher specs. But having said that, running Civ V on my current MBP with 8GB ram is really sluggish! I do like strategy and sim games like CIV and Settlers and play these primarily, but if performance wasn't an issue I would play driving and adventure games like Disney's Castle of Illusion, Lego's Batman or Star Wars Old Republic... So snooping around seemed to point towards the fact that the retina 13" may be a good choice because of the Iris chip (can't afford the 15" with Nvidia - and neither will I buy it just to play games), but on the other hand the rumoured 12" Air coming out sometime next year could rival the current rMBP. Now my question is: If you were in my shoes, would you upgrade now (and which machine would you choose) or would you wait for the new Air's to show up? Thanks!
