Old GPU as dedicated PhysX card

[Carolus Rex]

So i'm planning my new build, drooling over the new parts i want in the new machine and then i wonder what i should do with my old PC. And among the few things that i think can be salvaged is the GPU, which is an KFA2 GT 520. My question is if i can use that card as a dedicated PhysX card and if it will be powerful enough? And i'm sure the 770 will be able to do PhysX calculations own it's own just fine, just asking out of pure curiosity.

 

And if it matters, here is my build so far:

Just unnecessary power consumption, and could potentially lower performance.

it will perform worse than 770 by itself

hummm might not be much diffrence but could try it without and with out it and see if you get better performance with it or with out it

Keep it and test it out. I recommend Borderlands 2 to test the Physx. Sometimes a slower card dedicated to physx is slower than one card doing all the work. I think dedicated physx cards are meant for people who might have one slow card and another slower card. 

770 is a beast on its own.

You'd prolly get worse performance with that old GPU doing PhysX than with just the GTX770 alone doing PhysX as well. I recall using a GTX460 768MB + GTX670 (when I had a single GTX670 then) and performace was bad with the GTX460 dedicated as a PhysX card.

Hmmm, might aswell just try it out right? No harm done if it doesn't work.....

 

but thanks for all the replies guys! That was quick!

I am thinking about getting a MSI lightning 770, now I have a asus geforce gtx 570.

 

Will the 570 be a good PhysX dedicated card for the 770?

As I said earlier, it'll only cause unnecessary power consumption and may decrease performance.

the days of dedicated physx cards are over, my friend. The newer cards are beast enough on their own.

To be honest, I was interested to see if that would work so I threw in my old GTX 460 but I couldn't figure out how to get it to run as the PhysX card. I tested with FluidMark and the GeForce GTX showed in the list but I couldn't select it as the PhysX GPU.

 

I found instructions for what they called Hybrid PhysX like this (http://www.ngohq.com/graphic-cards/22136-how-to-fix-hybrid-physx-with-latest-physx-and-geforce-285-solved.html) but I wasn't sure if the benefits would be worth the hassle.

^^^  I think theres a Linus video where he shows different graphics cards as primary and physx. The only one that was beneficial was something like GTX 570 as primary and GTX 570 as physx. I dont remember perfectly, but it was something along those lines. You might as well SLI them.

Dont do it i tried that on my old pc and it does slow down the pc.

Sorry to bump an old thread, but I'd love to see if any tech or opinions have changed on the subject. For example, getting a 750 Ti to support a 780 as its dedicated PhsyX (assuming you can get one for a really low price).
