Hi! I'm thinking very seriously about getting a 17" iMac (; my only problem being that I'm not really sure that it would be able to do what I would like it to. I would really like it to be able to run Garageband w/o any noticeable hassles/lag-time. And, although I'm not at all a serious gamer, I would really like it to run Simcity 4 reasonably well. Has anyone had any experience w/ either of these programs (or similar ones) on the 17" iMac? If needs be, I can potentially wait for the next revision... but I don't want to!!
