I know it's designed for using identical (Nvidia only?) video cards in the two PCIe slots, but I wonder if the chipset infrastructure would allow one to install a high-performance bells & whistles multimedia sound card in one of the PCIe slots instead? If so, it might make sense to get an SLI board. Of course, I haven't seen one word about PCIe sound cards, so this supposition is moot for now, but it just seems way too specialized a system if all the setup can be used for is two video cards for an uber-gamer rig.
