GTX 280 + PhysX Card

Hello, i will be receiving my new evga GTX 280 video card any day now and I currently have an 8800gts 512. I barely understand PhysX but I understand that you use another video card to handle physx by itself? I was wondering if I can do that with my GTX 280 and 8800gts 512. I have a 750W power supply will this be enough for those 2. Also if anyone could give me a general idea on how to set it up/how it works and if adding a physx card wit the gtx 280 is even worth it to begin with.
Ty in advance.

My Specs:
Q6600 @ 3.4Ghz
4gb Corsair xms2/ 850
Thermaltake Toughpower 750W
nVidia 780i mobo

  1. i believe all you need to do is drop the GTS in the bottom slot, without using an SLI bridge. assuming its a quality power supply, it should do, but make sure it has enough power connectors... 2 6 pin and 1 8pin?

    it isn't really worth it atm unless you are F@H GPU clienting, but its better than throwing it away... that means you can turn off physx on the GTX 280 and unleash all that power purely for rendering, while the 8800GTS handles the physx aspect. it is helluva overkill for physx unless you're folding (a 9500/9600GT would more than suffice) but as i said, no harm in trying!

    good luck
  2. Heh, wish I was in your position. I'm hobbling my 3870 along until it dies. (Which is going to happen soon, what with all the lockups, and even the 115c Max temps. :P)

    Do hope you get it working though. Let us know how it goes.
  3. physx physics engine NVIDIA is probably going to get sqeshed because ATI and INTEL went havok and blizz new titles such as diablo 3 and starcraft 2 choose havok engine which is a major plus for ATI
