Hello all, I am planning on getting my first ever 27 " iMac! I want to use it for school work and to play World of Warcraft. What specs do you all recommend me getting? Is it necessary to get the i5 processor vs the i7? Do I really need to get the GTX 680MX ? Also, do I need to order a custom one from apple or can I go into a retailer the same day and buy it (bestbuy, macstore, etc.) For the money I would be paying, I want to be able to run WoW and diablo 3 on max settings (excluding shadows, I don't need them but wouldn't mind having them). The more money I could save the better regarding what hardware I need to get in it. Also, I was going to ask whether or not I should wait for the refresh of the haswell line, but I think I should take advantage of the sales going on as they reduce prices to make way for new inventory. Seems like the haswell won't do anything for gaming. Thanks for your help!
