Looks like I am the proud owner of a used BFG 6800 OC from the craigslist guy. I paypaled him the money on Friday and he said it would ship on Monday. Thanks Shok for posting it up.
Well I just got don installing that card from the Craigslist guy and I am impressed. I upgraded from a 5600 to a 6800 and there is a big difference. Had to move some hardware around (and give up a DVD drive) but I got it all to fit.
