AMD primary w/ Nvidia Dedicated Physx

[neon neophyte]

System list in my sig. I just added my old gtx 285 to my system in the hopes of using it as a dedicated physx card. My Primary GPU is a 6950. I refrained from this for a long time because it didnt seem worth it to me but I am bored and there are a couple games I play that use physx. (planetside 2, borderlands 2.)

Upon a quick glance I can see this isnt going to work straight out of the box, but I have heard that there is a way to make it work.

How do I go about doing this exactly?

Thanks in advance.
