The SkullTrail motherboard actually supports NVIDIA's SLI, which is apparently made possible by actually using a pair of NVIDIA MCPs on the motherboard itself. This isn't an SLI licensing deal; this is Intel purchasing NVIDIA MCPs and using them on its motherboard. 2-way SLI is supported today and Intel claims eventual support for up to 4-GPU SLI, depending on whenever NVIDIA releases drivers and product.
