So, after waiting almost 2 months, and after an obsessive amount of surfing the net looking for answers, i've decided to get a 27" iMac. My other option was a Mac Pro, but after WWDC only announced one and didn't give the price, i was happy to go with the iMac. But now! An analyst who has show a decent amount of accuracy in the past is reporting that he (Kuo) believes there will be an iMac refresh this month or less... http://forums.macrumors.com/showthread.php?t=1593052 I've waited two months (whilst trawling almost daily for any news), whats another month? I'm really hanging out for the update to the GPU, simply for gaming. If its going to be massive, it might be worth the wait, otherwise i'll buy now, sell around next years refresh and buy an updated iMac then. Thoughts/Advice?
