Yeah, the GA-P67A-UDX series all seem to support both SLI and CrossfireX. I think Intel has allowed SLI and CrossfireX on the same boards for a few generations though, no?

And yeah, of course 6970's in Crossfire are better than a single 6990/GTX590. I was just saying that if you're running 2560x1600 you better be using the best available single card or a at least a dual-card configuration. I think GTX 460's in SLI would be better than a single HD 6990 or GTX 590 as well. I guess I should have just said that you should use at least a dual-card configuration or a top-of-the-line single card for 2560x1600.

I'm wondering what we're going to see early 2012 for Ivy Bridge and PCI-E 3.0 for graphics cards...
