Hi All, I cancelled my original order 27Inch 6 months ago because of rumors of new IMacs. Anyway, Im confused about Memory 16gb or 32gb, 1 tb Fusion or 3tb. I thinks I will go with 3.4gb i7 and graphic 680mx 2gb. I currently have a 5 yr old PowerBook G4 ..upgraded to Leopard. Well, overdo for a new computer. Also have iPad 1, I will be mainly using it for video editeding, Youtube posting, photography ..currently have 4000 pics.. Will take Photography class in the summer. Other use will be...adding later iTV, office work, and basic use. I've been frustrated with my current computer limitations I want to make sure I'm making a good decision. Thanks for the feedback.
