Thanks for doing that. It looks like it is quite a bit faster. After about 15min elapsed I was over 1000. I had a constant 0.8 fps and had only 751 iterations. So the 400s are quite a bit faster if you consider how slow my 280 was going. 3.3fps is still pretty slow. I can see a very big difference in how far ahead of mine yours was at 15min. I wonder how an SLi setup will scale.
