I replaced my 9800 gx2 with a 4870 crossfire setup and was wondering if I would be able to use one 4870 and then the 9800gx2 for PhysX? Does the GX2 even support PHysx? Its more curiousity than anything.

The latest driver supposedly enabled Physx for 8 and 9 series cards. Not sure how well it works for a dual gpu card like 9800gx2 though.

As for using it for physx with 4870, it doesn't make sense. 9800gx2 outperforms gtx280, and far outperforms a single 4870. It would be too much of a downgrade. Is Physx really that important? Personally, I wouldn't even get the dual 4870s to replace it. A mere 20% average performance improvement just isn't worth the $550 price tag. :p

Thanks for the reply, I was only curious to know if it worked, if it does then it means that it would probably work using the 4870 X2 and the 9800 GX2 for physx.

Yes, it should, assuming no driver conflicts. Drivers is a big issue here. Having both nvidia and ati drivers on the same OS is not a good idea. People who dedicate a graphics card for physics usually use two nvidia cards.
