I can get a 24" iMac refurb for $1699 with the 7300GT or I can spend the extra dough and get a new 24" iMac BTO with the 7600GT for $2040 with Education Discount. I've seen all of the benchmarks between these 2 cards and it seems that the 7600GT just about doubles the frame rates of the 7300GT, but what do they really mean in real application? I do a lot with photography (Aperture, Nikon NX, Photoshop), and some layout, but nothing too taxing. I also want to dual boot into Windows XP and play a game here and there. I just sold my Dual 2.0 G5 and never had any issues with it in terms of processing power. I played a few Mac games on it and the 9600XT faired pretty well, but nothing spectacular. So I guess the question is if the 7600GT upgrade is worth the extra $340? I could just about buy an XBOX 360 for that, but I do enjoy games more sitting at my desk. Any thoughts?
