I really want a new 24" imac I currently have a 2ghz 17" ppc imac with 1 gig and 160 gig full hadrdrive. I want to buy the new imac but i dont know if it will be enough of an upgrade or if I should wait until they put a new processor in it. I was also thinking about buying an external but I am holding off until I make up my mind on the new imac. Can anyone give me some buying advice or if they are going to put a new processor in the new imac in a month or two. Thanks
