I just found this, it enables us to use dissimilar GPUs in SLi (like ATI). Do you think it will allow us to use quad SLI for mid range cards like the 670 and 470?

My feeling is this won't work very well, and it looks like it doesn't.

I'm almost positive, the GTX 670 can in fact do quad SLI, it was not possible at launch but it will be with driver updates. (I think)
