AMD’s new RD790 chipsets will bring some cool features but one really interesting one according to the Inquirer is the use of 4 graphics cards in a crossfire-like set up. They will have to be X1k and X2k series cards however.
The motherboards will sport 4 full length PCIe slots running 4 of them at 8x or two of them at 16x.
OCZ has some pictures of one of the motherboards that you can check out here.
I don’t really see the use in 4 graphics cards unless you are doing some kind of crazy work that would require you to have 8 monitors set up. That just seems like way to many monitors to me.
