Its using an older AMD chipset, which Nvidia did not grant them the license to support SLI on that chipset.
In the past, AMD used Nvidia chipsets to implement SLI on their products, but after AMD bought up ATI, Nvidia started to get worried that they were being edged out of their market, so they locked out other vendors from offering SLI on their chipsets. Intel's SkullTrail was the exception, having purchased a license from Nvidia for that board.
Beginning with the newest AMD 900 chipset, SLI is again enabled, but that doesn't help me now that I have bought a second card.
