HD 8000 was a rebadge of HD 7000 for OEMs. I have an 8950, however it crashes under any load, as far as I can tell the GPU core was heavily degraded or something as it seemed okay at like 1250 mv and 500 mhz. I guess I could just flash the bios from my HD 8950 on my reference HD 7950, but I also want to bench it on hwbot and I don't believe in that kind of thing. Hopefully I can find an 8970, but they're hella rare. 8950s are easier to find but have an inflated value vs a 280 or 7950.
