I've been planning an AM3 build and bought this board a while back with a Phenom II X4 965 originally intending to run an ATI video card. But as of late I've been very intrigued by PhysX (plus CUDA as I'm also a SETI cruncher) offered on GeForce cards. While this board isn't SLI capable does that mean I can't run say a GTX 275 as it's a double layer card (which I thought meant it was an SLI in 1 unit from the factory, but I've seen seen differing statements on this). Or will I be OK as it's "one" card and as long as I don't use another I'm good? Since you need the board to do the bridging between cards, since it appears they stopped doing it with that little bridge board.
