R9 280X Vapor-X + R9 280X Toxic crossfire - is it possible?

Hello community,

been a silent lurker for some time, but now I have an actual question myself. I am interested if you are able to crossfire 2 videocards with minor difference in clock speed like:
R9 280X Vapor-X and R9 280X Toxic in my specific case.

Yes, you can run them together. They will just run at the lower clock speed.

yes but your clock speeds may be different, just use afterburner to sync your speeds and make sure your pc/powersupply is capable of handling them
