Great card, this is a 7900GTX core with slightly slower memory (NOT a 7900GT core). Benchmarks are almost the same as a full 7900GTX, and apparently overclocks well (though I've never done it).
Comes with a limited lifetime warranty, I have the receipt and have never registered the card.
Asking $120
