I'm in the market for a new computer and I'm considering a mac. I'm looking at the 21.5" w/ 2.7 i5 and the 6770M. I'm not a hard core gamer but would like to be able to play Star Wars: The Old Republic on medium to high settings with no lag. Is it possible? Has anyone played the beta or Early Access on your iMac and what was the game play like? Thanks.
