Im confused on the DFI lanparty skt 939. I was looking at the ones that support pci express and there are so many different ones. They say thaey support pci express x 16 (2). Does that mean that you have to use 2 video cards? And whats the deal with pci express x1, x4 and x16? If I wanted to run 1 evga 9600 pro pci express which 1 would I be looking at? Possible to give me a link to one? Obviously on N.E.
