I have one of these infamous BFG 7900gs that has a GT chip, and fully unlocks to 7900gt w/ rivatuner. I replaced the stock cooler with a Zerotherm 710, and verified that it was a GT chip after cleaning off the old paste. It performs quite well, up with the best of the GT's. What do you think it's worth, given it's a rare item, and it has a nice aftermarket cooler? Would there be anyone here interested?
