Guys i think i might found a working bios, im at work now so ill try it out tonight
Reference 7970 has the AMD logo near the PCI-EX connector:So far i couldnt find any R9 280x with the AMD logo meaning its a reference PCB (Of the hd7970 probably)
But i finally found this one:
MSI Radeon R9 280X Gaming 3GB
So there is a small chance the MSI R9 280X 3072 MB BIOS (Gaming) bios might work,
Becuase it looks like the R9 280x is a reference board, and they dont make reference boards for the R9 280x.
So i think there is a high chance it has to be a HD7970 pcb.
So when i get home tonight ill test this bios out: http://www.techpowerup.com/vgabios/146769/msi-r9280x-3072-131009.html
