Windows 7: 3D Mark 11 - Problem with Physics Benchmarks

3D Mark 11 - Problem with Physics Benchmarks

Hello guys.
I just finished upgrading to new mobo (MSI 990FXA GD80 V2), CPU (FX 8320 4.5MHz) and crossfire 7850 cards. Upgraded from Asus M5a97 Evo, Fx8120 and single 7850
When running 3D Mark 11 I get very good FPS in all tests but I crawl at 3-5 fps in the two last ones which include Physics.
I used to get 20-25 fps with a single 7850, FX 8120 (4.3 OC) and old mobo.
What can I do to fix this? Can it be related to PCI-E voltages or frequencies set in BIOS? DirectX installation issues?
Your advice would be very much appreciated.

What happens if you disable Crossfire?

And have you installed necessary mobo drivers?

All mobo drivers are installed.
Thanks for your help,
