590 GTX + Physx GPU Do i need it?
Hey everyone. I have a 590 GTX which i am very happy with.

If i get a GPU like a 550ti for Physx, would i see major imporevemnts in FPS or should i stick with my 590?

Also will my GPU run hotter if i add a second GPU in my setup?

Thank you.

i don't think you will get any noticeable improvement at all, and yes both gpus will run hotter than normall also your PSU will need to be strong enough for 590 + 550 ti.

Depending on how is your physx performance sometimes using a dedicated gpu with less power than your actual GPU can cause lower framerate than normal.

Try dedicating one of the GTX 590's GPU for PhysX and check. If you get any drop in performance then I would suggest you to go a dedicated PhysX or else stick with GTX 590 only.

Generally speaking you want at least half the CUDA cores your GPU has. Since your GPU has 2x512, I'd say you need at least a GTX 460 or 560 (regular) minimum. A GTX 550 Ti only has 192 Cores, and a weak 192-Bit Memory interface, and it'd probably drag your 590 down performance wise if it were set to handle PhysX.

Honestly, it depends on the games you play. If you're playing a lot of PhysX titles, see about snagging a GTX 560 Ti cheap (used) and use it, that'll be more than enough.

I have the same card, GTX 590(HYDRO)...
Can I use a GTX 670 for dedicated PhysX gaming??
