Interesting article over at Extremetech.com:

SLI vs. Crossfire: Hi-res Slapdown (http://www.extremetech.com/article2/0,1697,2009946,00.asp)

What it comes down to is this: QuadSLI seems to shine in situations that are fill-rate limited, but don't require really extensive shader work. As the complexity of shaders goes up relative to the memory bandwidth requirements, the two-GPU setups do better because they're clocked higher and have less driver overhead.

Their 3dmark06 score seem in line with what I'm getting on my rig.

Nvidia needs to release more mature Quad-SLI drivers in order to save face against 7900 GTX SLI...

In our overall showdown between ATI and Nvidia for extreme hi-res gaming, we're going to have to give the edge to ATI. At $900, the new X1950 Crossfire setup generally outperforms the others, especially with AA and AF applied (and isn't that why you would buy such an expensive graphics setup, to enable features like AA/AF?). The X1900 Crossfire solution is actually fairly impressive. Sure it's slower than the X1950 at the very highest settings, but often the difference isn't huge, and at $700 it's substantially less expensive than any of the other dual-graphics setups tested here. If you do play a lot of OpenGL titles, then the 7900 GTX in SLI mode is a more robust solution for high-end gamers with high resolution displays. But most games today use DirectX, and ATI has the edge today.

Crossfire seems to have and edge on performance (X1950) and price (X1900).

Who says that drivers alone would take care of it? This Quad SLi stuff still seems like a very unproven technology to me.
