They seem to be selling for ~$450 on ebay.

$150 (includes shipping, US only)

Two caveats:
1) don't buy it with the intention of resale
2) use it to crunch for the team when not otherwise being used (work, gaming, video editing, etc)

Note: This is a long card, so make sure it fits in your box (phrasing!). Also, needs two 8-pin pcie power.
