But once all that's sorted, all we're going to need are some motherboards to accommodate the two cards, as the only setup that we know of with the appropriate slots is Intel's dual Xeon "Tumwater" chipset.
However, while not wanting to give away too many details, some motherboard manufactures have hinted at the possibility of more options at a later date. One example was Andrew Cotterill from Epox, who told CPC that Epox, "may manufacture a board based on nForce4 with PCI-E 16x and 8x connectors for SLI", and said that he expected nForce4 boards to be circulating by the end of this year.
