Hi guys! I ran 3d mark with only one 7870 XT installed and got this.

With two it should be a heck of a lot better right? How about worse!

Well, from what I've read around the forums, 7850/7870s don't do so well in crossfire.

And your motherboard doesn't support true crossfire. It's only there for multiple displays. One lane is running at 16x, whereas the other is running at 4x.

It's not a 7870. It's a tahiti card.

Also it shouldn't do this bad. In furmark I can see the scaling but not here.

Contrary to what anyone else says, MY Powercolor 7870 tahitis in crossfire perform amazingly well. I've NEVER had a problem with them. He is my latest score on 3dmark 11. You tell me if they don't crossfire well. This is 3dmark11 1.0.5

Also, run the 7870 tahitis on 3dmark 11 performance both single and crossfired. Me thinks your CPU is holding you back. Let me know your results.....jimbo
