Any have any experience with this board? It is supposed to work with both NVIDIA and ATI cards but Im wondering if it would be a way to utilize both a gaming card and a workstation graphics card? I might be buying one of these for my gaming PC at home so I may end up trying it out anyways but it seems like an interesting idea. Any thoughts?
