Asus M4A89TD Pro/USB is an AM3 board that with latest bios updates support or should fully support old FX-X1XX. Bios is 3029, not beta, available here:http://www.asus.it/Motherboards/AMD_AM3/M4A89TD_PROUSB3/#download
Asus has already said it won't support this board and the others like it (as Crosshair Formula IV) to fully support new FX-8350/8320.
Actually community has discovered those CPUs work on the board:
At this state we don't know if they are stable too, but I think a modded BIOS thought for them would help very much.
So this is the request.
