I would get the i7 for longevity if nothing else. It won't make a huge difference, but it will make some difference, which will become more and more noticable as time goes on. I opted for the 2.33GHz iMac back 2006 over the 2.16GHz and it has given it more life in 2012. That's how it works! I would get a Fusion Drive and i7 with 2GB GPU if I were you. In prior generations, the i7 had hyperthreading and the i5 did not (8 threads vs 4 threads) which can make a huge difference for certain applications, including Creative Suite apps. I'm not sure if the current new gen i5's have hyper threading but if not then that's a major reason to put down the extra $200 for the i7.
