Setting up Physics card with ATI main display?

was bored, ordred a xfx 5870 to use as my main display.

ATM i have a gtx285.

After i install the 5870 would i beable to keep the gtx285 as a physics card? or no?

There is a big difference between a physics card and a physx card. On games you play that utilize the physx physics engine, do you really need the extra 2 fps?

You know what I was talking about.

Some of the newer games that take advantage of it like batman and a few others are showing really good gains with a dedicated physics card.

And I already have the nvidia card so its not like im spending extra money.. It would just go to my girls computer if I dont use it.
