wow, from the techreport article on mobos: "Like previous Intel chipsets, the X58 Express has full support for AMD's CrossFire multi-GPU scheme, including three- and four-way configs. SLI will also be supported—a first for Intel platforms (not including uber-expensive Skulltrail systems). However, actual SLI certification will be done at the motherboard level rather than being tied to the chipset. Certified motherboards will have a special key embedded in their BIOS that Nvidia's graphics drivers will check prior to enabling SLI. To date, Asus, DFI, ECS, EVGA, Foxconn, Gigabyte, and MSI have licensed SLI for their X58 boards."
