Building a high end rig with a friend and are trying to decide on a few MBs. He is going to be using an ATI 5970 video card, so does this mean he should stay away from boards with the NF200? Hes basically between the P6T6 WS Revolution, the EVGA Classified (3x not 4x). Also getting strong consideration is the all black EVGA board that is only $225 on Newegg. Honestly he will probably only ever be using a single video card, but he likes the idea of being able to run both SLI and CrossFire. To the PhysX components of the high end MBs work with ATI video cards?
