This graphic is really useful. After toying about with this MBA more, I think it will be absolutely perfect for work but seeing as the game performance is decent... if during an extended session I am going to drop maybe 25% of frames, I might as well upgrade to the MBP. These are all edge case scenarios, but since I am lucky enough to be able to choose either without much fuss... I might go for the Pro in the end. The final question is what is the fan like, how often does it come on, how loud etc etc. If its stays fanless for everything but a render or a gaming session, then I'm sold.
But amazing value for the base MBA.
