I know im dragging this mb thing along, but this (Newegg.com - ASUS P5N32-E SLI Plus LGA 775 NVIDIA nForce 650i SLI ATX Intel Motherboard - Retail) looks like the best bet, sli at x16 x16 with the 650i chipset. Plus it overclocks, etc... I know what mb's have been suggested, the story behind each, but this looks good for future sli. I read in the link b1gapl posted that its "not a true full sli" because of the bridge used, im not sure if this matters but this is the only mb I can find with full sli and 650i, etc...
