I would say you’ll be better off with the MacBook Pro. If extreme portability is not a very big requirement then the MacBook Pro is better than the Air in practically every way. Also with some games not receiving very good mac ports, like Firmament, Layers of Fear, etc. performance on the MacBook Air is not as reliable as the Pro. You can expect a minimum of 30-40fps at decent settings at just about any game you throw at the MacBook Pro.
