I have a 2013 MBA, recently installed WoW to play with some buddies and to my disappointment, a 10 year old game gets 15-25 fps on mid-high settings in new areas. 10 year old game... Nice. Do the current MBPs perform? I mean the 13", I can't afford 15", the price hike is ridiculous. Or is it about the same and should I just wait for Broadwell?
