I am about to order a new 27" and can't decide which graphics card to go with. I have been keeping an eye on the other comparison threads but haven't seen anyone with my setup. Alli use mine for is HD encodes with Handbrake, iPhoto and iMovie. I will never use it for gaming. From what I can tell the programs that I use won't take advantage of the 680 and I'd rather put that money towards some extra ram from crucial. Opinions?
