Yes, Bitmit would be good.
the 5870 I get no signal and does not show up.
the 5830 and 5850 show up but do not get signal once windows starts it downloads a driver and then I lose the video on a 5870 that works
Is the 5870 you're selling the one that loses video once windows starts? Does it show the BIOS correctly, and does it show up in the device manager (probably as "unknown device")? If so, I'd be willing to buy it alone for 0.1-0.15 to use with vanitygen, if you're willing to sell them individually.
