I've just had an MSI GTX 780 Twin Frozr arrive to replace my SLI GTX570 setup.

I know a GTX 780 should be able handle the PhysX part of an enabled game on a single screen without a problem, but my question is would it benefit from using one of the 570s as a dedicated PhysX card considering I use 3 monitors at a resolution of 5760x1080?

My CPU is an i52500k overclocked to 4.5Ghz and 8GB of RAM if that helps any.

Thanks in advance
 

+1 to MM on both parts.

It's actually a good logical reason to use that extra GTX 570 for PhysX and squeeze as much performance as you can for your surround system. Just make sure that you are playing GPU accelerated PhysX games on a regular basis, otherwise you'll be adding heat, power consumption, and noise for no good reason. Make sure you have a good enough PSU to run two video cards.


By the way, it is nice to not get the usual AMD fan response: "It's not worth it, too few games feature PhysX, OpenCL is where its at, Mantle is awesome, PhysX sucks, you can run PhysX on your CPU, etc." (those are actual recent responses to questions about PhysX).
 

Well I just got a GTX 780 Ti and I may try to plug in my GTX 580 as a PhysX card. Wait, actually typing that out sounds a lot more absurd than it did just thinking it in my mind.
