Hi MacRumors, I'm in the market for an iMac and I've found a 21.5" model with an SSD and the 750m GPU at a price I like. I'm trying to decide if I should go ahead and pull the trigger on it, or if I should try to wait for Apple to update the line in October. Here are some things that are influencing my decision: 1) My gaming PC is on the fritz, and my backup computer is painfully slow at everyday tasks, so I 'need' a new computer. I could handle waiting another month, but if the new iMacs weren't shipping until late November, that would be longer than I'd like to wait. 2) I'm not interested in a 27" Retina iMac (or, more accurately, I don't have the budget for it) 3) If I knew now that the new iMacs would have dramatically better GPU's, I would probably wait. This is the main thing holding me back. 4) If any other component significantly changes the value proposition - for example, if the new iMacs will include fusion drives or SSDs standard, at the same price point - I would probably prefer to wait. Knowing these things, would you recommend that I purchase now or wait until the line refreshes in the next month or so? I know we can't see the future, but I'm hoping that some of you might be able to make better educated guesses than myself. Thanks for your time!
