Second ATI physx card?

Last response: in Graphics & Displays

Hey guys,
So I'm upgrading to an HD 7870 soon ! :D  Then of course I'll have my old HD 4770 available for other kinds of nonsense. So, I was thinking. would it be possible to use that second card to handle physx? Like, I know its supposed to be an Nvidia thing, but I saw the option for physx somewhere on my current ATI card's settings, can't remember where I saw it though! GRRR (there were four boxes to tick, Direct Compute, Open GL, i think, Cuda and physx) If this were indeed possible, how would i go about setting it up and connecting it. I have a strong enough psu.

Thanks guys :)

Looked exactly like that except I don't have GPU-Z... Got CPU-Z though no option like that ,however. Maybe hardware infor?

sure whatever, but the point is the software is showing what the card is capable of with those ticks, it is not user selectable setting or something you could change...

aaah oky makes sense thanks! :)  I just thought that since Physx can work on a CPU it would work on an ATI card. Sure it wouldn't be optimized but I wouldn't need it to be since the HD 4770 would properly be plenty powerful enough to run it. Also I read somewhere that you could but I could be mistaken... Thanks anyway! :D

That is showing how you can run a NVIDIA card as like a secondary card with an ATI card as the primary GPU. So like if you were to run your soon-to-be 7870 with say.....a GTS250 like I have, they have hacked drivers to do so (I've done it)

I read further after I posted and sort of guessed that, but I just wanted to make sure. BTW is Physx such a big improvement or is it just hype? I could imagine having better physics calculations would help a great deal in racing games, but we're already so close to real life, is it really needed?
