Not possible to CrossFire. You need either two 69xx series cards or two 58xx series cards to CrossFire. The 6950 and 5870 are incompatible.

You can run them both in the system, but as erocker said; no way to crossfire them.

That's not possible.

I was playing Metro 2033 on that rig about an hour ago..:ohwell:
Sure, that doesn't mean the cards are working in CrossFire. It's not possible with two different GPU's.

Just wanted to also reinforce the truth. There is no way to crossfire any of the 3 GPU's you've listed. It just doesn't work.

That chart has all the info you need for relevant GPU crossfiring.

I would sell the 5870 and get another 6950 :)

The 6900 series scale like champions in crossfire, FYI.
