1. Install both sets of GPU's. Ati first then Nvidia
2. Attach GPU's to monitors (2 preferably as you can see what you are doing)
3. Click windows\control panel\all control panel items\display\screen resolution
4. Click detect displays
5. Click and switch to Ati display extended to Nvidia if not already
6. Open CCC panel
7. Disable CrossfireX if enabled
8. Switch to Nvidia only display
9. Unplug the Ati cord and enable PhysX from the nvidia control panel, leave open
10. Plug back in the Ati cord
11. Detect displays in the windows display control panel
12. Extend the display over to Ati
13. Click on the Ati display picture and check the "Make this my main display".
14. Click on disable and enable of PhysX and hit apply. Important, if apply doesn't appear at this stage, you won't have PhysX!
15. Leave on extended display
16. Run vantage 3D mark CPU test 2 to confirm Physx enabled
17. Enable CrossFireX, confirm again with CPU test 2

thanks for the guide
i've just tried it with an 8800gts 320mb and a single 4870X2 but when trying to run the 3dmark vantage test, i get an error if i leave the desktop extended for physx

std::exception
SetFullscreenState failed

i'm running the 180.48 drivers and the 9.1 cats

Try 181.22 WHQL drivers, everything from 18x previous to those gave me problems.

I have exactly your hardware configuration for graphics cards Pyr0 and I just got (and fixed) this error. I had the Prerelease WDDM1.1 drivers running on my 4870X2 and the nvidia-provided WDDM1.0 drivers running on my 8800GTS 320mb. Run dxdiag and check the display tabs to verify what each of your cards is running - if your ATi card is using the 1.1's then do an update driver (if you already have either catalyst 9.1 or 9.2s installed, if not install them) and choose one of the catalyst-provided drivers from the list. Voila, vantage runs, and physx appears to be working!

Would be nice if more people would try this, see if there is any problems, bugs or other ways to do it.
