You can use it on any board as it has it's own pcie 1 bridge. Just can't crossfirex with it.

The x2 can be put on any mobo with a single 16x pcie slot because it has a pcie bridge to do crossfire internally. The only limitation with an nvidia chipset is that you cannot use 2 x2's in crossfirex.

It will work perfectly on that motherboard.

But because it's an SLI motherboard you could never buy a second 3870X2 and run crossfire.
