Theres more to it than the HW in that link. If it was the cards only, then itd all be the same. I think its drivers, plain and simple, and so far, i7 can take advantage of those drivers much better. I also believe this will change in older quads favor as both ATI (especially needs to) and nVidia work on their drivers for optimizations for quads. As they get better, its hard to say we will see more from i7, but definately from other quads. Time will tell on this, I just wouldnt put it in the bank this is due just to i7s ability at this point
