Dedicated PhysX Card?

[RadiatingLight]

I will soon be purchasing a GTX 1070, and was wondering if using my old GTX 770 as a physX card would be good? Would it possibly bottleneck my 1070?

How much performance will i gain? 

Thanks for your help

bad idea, using more power for no performance increase.

 

physX is not a thing anymore

Mafia 3???

Yeah, you'd use more power, but in games that use physx you would see a small performance gain

Some games still support it, and the card would use almost no power if a given game doesn't support physX,  right?

How much is small?

Would it be more worth it to sell my 770?

Is anything using a Physx card can lower FPS

okay if you want a 1% performance increase do it

even on supported games youll get little to no benefit, all you're doing is raising your power bill, and if you're a kid i know you dont care about that, but your parents will

There's a certain cutoff point where a dedicated PhysX card becomes a bottleneck to the other card. I used a GT 630 as a dedicated PhysX card alongside my GTX 760, in games like Mirror's Edge there was a decent performance boost at high resolutions where my 760 was being ran at 100% with PhysX off, and because the game didn't have a massive amount of particles, the 630 could keep up and not slow the game down.

 

The performance boost you'll see all comes down to the usage of your main GPU and the target framerate you want. If your GPU is being maxed out running something like Borderlands 2 at 4k (Easy example I used myself) with the PhysX turned off, then having a dedicated PhysX card will let you keep those framerates so long as the PhysX card can calculate at the framerate of the main card, if that makes sense.

 

Generally speaking, you'd be fine having it sat in your PC as a dedicated CUDA/PhysX card for a bit of a performance boost where it'll be used, and it should clock down low enough when not being used to make a negligable difference to power consumption. Plus you get a lot more display connections if that's your thing
