I'm a graphic designer by day, but would like the option to start producing music (logic pro maybe?) and will most likely use after effects, final cut, and some quasi demanding games. I've been battling with the decision all weekend. Should I wait for the new iMac refresh? The prices for refurb imacs are very sexy right now. The mb has been looking very tempting too. I really enjoy the size. Can the mb push pretty much everything I need it to without hiccups? Will I need to just take the plunge into pro-ville? Any suggestions based on specs and experience?
