Can I use an 8500GT 1GB for PhysX and run 3D on a 4850?

I know it sounds silly but according to the Nvidia PhysX Driver readme, this concept isn't out of the question. Now Nvidia is supposedly going to get PhysX enabled on ALL G80 based boards so I'm thinking I could just toss in an old 8500 or 8600GT/S as a physics co-processor. Has anybody hacked the new 177.39s to work with older G80s and have any of you used PhysX on one card while enabling 3D on another?

If this works then I will one day own an Intel AMD ATI Nvidia based computer in the form of a Nehalem CPU with Crossfire 4850/70 and a cheap Nvidia PhysX GPU backing up the fun. I already installed Nvidia's PhysX driver on my system to see if there were any ill effects with my 2900XT and there were none. It works fine. Now I have to see if a system can handle both Nvidia display drivers (for physics) and ATI display drivers all at once without exploding.

If anybody just picked up a 4850 to replace an older CUDA enabled Nvidia card (like an 8800GT or crappier) for your Intel system then do some testing for us and let us know the results please. :D

should work. Planning something similar here.

i think Vista only allows one display driver to be installed at a time. *if* it's possible, and i don't know if it is, it would probably only be possible on Win XP.

It would require NV to release some PhysX-only driver.

I've tried... it doesnt work.

tried with the GTX 280 + my 9800GTX.
the second card just doesnt do anything.

whats most likely gonna happen, is they will release SLI + Physics sometime soon to enable that.
but given the limitations of SLI, that would probably still mean you have to have 2 identical cards.

That's what I was thinking of doing, or similar to it. I have an x38 board with a GTS G92, and I was thinking about just adding in a low end 8 series card to do physics. I hope nvidia can get something like that working.
