sort of. theres a gigabyte model that cheats to get 2 PCIe video cards on a 915P I think it was. But there are no true SLI Intel based boards yet, nVidia is prepping one though
Well there's the soon-to-be-released nForce5 board by eVga or you can always go the server route. Golden question is ... which mobo will cost more? ... of course there's always the ALX route but thats uber expensive
