Dedicated PhysX with GT 720?

Dethan1999 · Sep 8, 2016

Hi!

I have a GTX 960 at the moment, and was reading about a dedicated Physx card. Lemme get this straight... If I were to have a separate dedicated Physx card, it would reduce the load put on my GTX 960 and would improve my FPS, right?

I have a GT 720 laying around and was wondering if it would be worth putting it in as a PhysX card. Would that take some load off my GTX 960? Another question is... If a dedicated PhysX card is under heavy load, would it hurt my FPS? I can only imagine the GT 720 wont really be able to do much... Would the dedicated PhysX card only preform to the best of its ability and let the GTX 960 do the other work the GT 720 couldnt?

Basically, I'm just trying to improve my FPS. If using a GT 720 as a dedicated PhysX card will hurt me FPS, then I'm out!

Thanks for any help!

that's not really true.
the 720 is very weak card and using it for physix will actually reduce the FPS as it will not be able to process the physix fast enough.

It would only affect games that use PhysX.. (not many)

In this case, using a much slower card like the 720 will make performance far worse.

An extra card will also take away pcie lanes, increase heat, etc. All those things will end up just making it slower.

Even benchmarks of using a 750ti as a dedicated phsyx card resulted in worse performance.

Was looking at doing the same thing as you, but the benefits weren't worth it for the price of another high-end card.

Faux_Grey :

Depends, in many cases a 750 Ti does help. However, it's also a more expensive card, and not worth using just for PhysX.

But yeah, slower PhysX cards just ruin performance. Linustechtips recently released a video where they looked at a GT 730 for PhysX, and it was just bad.

The GT720 will slow down your system's performance in games that require Physx, it is much faster to use the 960 will give you higher frame rates while processing physx.

Here's an interesting video about it:

I have a dedicated Physx card, which is a GTX 750. What matters the most are CUDA cores and clock speed, neither of which a GT 720 has much of.

A dedicated Physx card is definitely worthwhile, but I wouldn't consider anything less than a GTX 750.
