If you're looking for an Intel SLI motherboard, you may want to drop by Hexus. I've thus far skirted around the whole raison d'etre of this board. It's the first retail LGA775-based SLI-capable that's crossed our path. 2 PCI-Express lanes that shunt down to x8 protocol when 2 PCIe NVIDIA GeForce 6800-series cards are run in tandem. Double the cards can mean, in certain situations, almost double the frame-rate fun. You can simply run the board with any single PCI-Express card and it will function as a decent motherboard. Strap in 2 GeForce 6800 Ultras, for example, place the bridge connector on top, and the ForceWare OS graphics driver will pick the second card up. There's also no need to manually define, through the use of a reversible key, single- or dual-card use here, either. It's the first digitally switching SLI board that I've come across. Now that's quite interesting. Read the full review over here.
