Using a 970 for Physx

[tornadog]

So I am upgrading to a 1070 from a 970. After getting some low ball offers for the 970(some guy had the cheek to offer 100 bucks for it), I figured why not keep both cards and dedicate the 970 just for physx. Is that a good idea. Has anyone tried this. I got the idea from the NVidia Funhouse reviews where they were using 1 1080 for graphics and another 1080 for physx!!!

It might be handy in that particular situation, but I can't see many mainstream uses where a 2nd card would be necessary.

Maybe if you had 2x 1070's in SLI a 3rd card would be desirable to avoid the microstutter that can be introduced due to only one of the cards taking longer to finish the frame because only one card is used (or at least used to be used) to calculate PhysX. Not sure if later pre-emption/frametime sync developments have alleviated this yet.

Back when I had 2x 9800GTX+'s I used to dedicate 1 of them to PhysX for Cryostasis and Arkham Asylum, but when Fermi came along it was no longer necessary.

The only way to be sure is to try it in a variety of games that support PhysX and the like.

The other thing to bear in mind is that the 970's shaders will be quite a bit slower than an overclocked 1070.

Are there any new games that actually use physx? I thought the proprietly nature of it turned off alot of developers and relegated to just a few niche games.

Using a 970 just for physx seems a but overkill no? U really need a 4GB that just 3 months ago was high end to render physx?

The issue is moot now. I was able to sell the 970 for a decent price🙂

Would be interesting to see if other compute based loads like some gameworks features or vrAudio could be offloaded onto a secondary card.

It was moot before you even asked IMHO.
