ASUS P7P55D-E

Hi, im building a computer for a friend and im interested in the ASUS P7P55D-E listed here: http://www.asus.com/product.aspx?P_ID=9i872VNaAILRp8bS

If you scroll down to the specs, it says that it supports "Supports ATI® Quad-GPU CrossFireX™ Technology". Would I still be able to use a single NVIDIA video card? I just wanted to verify before I get this board. Thanks


BTW: I was thinking about getting the 9800GT.

Not a problem, you can also mod the Nvidia drivers too if you do want SLI (works great).
