Hi there. I'm a graphic designer mostly for print. Can anyone suggest the best performance configuration on the imac. I work mostly with cs6. That is.. Indesign, illustrator, photoshop.. I don't create video. I use suitcase, acrobat, occasionally Bridge, most days I might have most of these open.. Do I benefit from i7 over i5?, would 3TB Fusion suffice over 512 flash? do I really need the better graphic card. The differences are important as I also need to buy CS6 which is also the best part of 800 quid, so I am on a budget and can't afford to max out the 27inch just because I can. Thanks a lot guys.
