Galaxy has tweaked the enclosed card to reduce power consumption (and thus heat). It is based on a 55nm process with 216 stream processors, 896MB of GDDR3 memory across a 448-bit memory interface, has a core clock frequency of 576MHz, 999MHz memory, 1242MHz shader, supports DirectX 10 and 3-way SLI, and pulls power from two 6-pin PCI-E connectors.
I haven't been able to find any information about a price or availability. I've attempted to contact Galaxy and will update the post if I hear back. In the meantime, you stumble across this information feel free to clue us in via the comments.
