So I'm in the market for a new computer and was looking into the iMacs and my price range will allow for either the baseline 21.5 1199$ iMac or the step up 21.5 1499$ iMac. So I plan on mainly using said computer for Photoshop, Illustrator, After Effects, & Premiere Pro. that and I do a little mild gaming here and there nothing big and not all that often. So I was looking at them and saw the only differences really were the 1TB drive which is good and all but if I ever need more space I can get external drives. on the higher end you get a 2.7ghz opposed to the 2.5 which again isn't really that big of a preformance boost from what I can tell. The main thing I saw was that on the higher end of the two options you get a a improved graphics card the 6770 opposed to the 6750. now my question is this. is it that big a difference in preformance to warrant buying the higher end of the two. that combined with the other improvements I listed.
