Just bought an X800GTO2 from NewEgg. This exact card:
SAPPHIRE 100130 Radeon X800GTO2 256MB GDDR3 PCI Express x16 Video Card - OEM
I couldn't find it on NewEgg anymore, but there is a VIVO card just like it for the same price. In any case, mine Bios flashed to 16 pipes with no issues, and the Trixx overclocking utility bundled with the card came up with 560 Core and 565 Memory as the maximum overclock. I have it at 520/540, which would match an X850XT. Overall, a great buy for $208. Smokes the 6800GS.
