Allright so my single 1.6ghz g5 Mac pro is finally ready to be put out to pasture. If thats any indication of how long I keep computers around before I upgrade then do you think upgrading to the i7 quad 27 inch from the i5 quad 27 inch would be a wise choice? I mostly intend to use the new imac for school, some games (Starcraft 2, DIablo III, Civilzation etc.) Not really doing anything other than that. But if I intend to keep the computer for an age do you think the i7's hyper threading would be beneficial to me later down the road? Help me HellHammer, you're my only hope!
