    Hello everyone
    I have a graphic card (Gainward Geforce GTX 580 GOOD EDITION) and I was reading around that it's possible to use a second graphic card dedicated for Physx, can someone explain me which are the advantages of doing this?

    Dedicating PhysX processing to a secondary card speeds up your primary GPU and eliminates ~attempted~ PhysX processing by your CPU.
    It makes games with PhysX coded into them run faster and smoother.

    The downside is additional heat inside of your case.

    bring the price down?

    I'm not sure of the process, however I do remember a thread on TPU somewhere outlining it. Someone else familiar with multi-gpu setups might remember/

    Go to the NVIDIA control panel by right clicking the mouse and selecting it.
    Once there, look under 3D settings,.....

    select: "Configure SLI, Surround, PhysX"

    In the box to the right, under PhysX settings, select the second card in the drop down menu and tick the box underneath that says "Dedicate To PhysX"
    Save, exit and reboot the system and that should do it

    It's useless. Just using your 770 alone would be enough, but if you were to do it you wouldn't even need more than a 610 to give you graphics card level physx. It's not worth it with that card and many would argue that it's not worth it in general since such few games support it.

    +1 and also .... the PhysX enabled games ... are quite a few ...

    for me only Mass Effect 3 asked me to install the Ageia PhysX driver (calculation by CPU ... o_O ) as i have a AMD GPU no games that need it runs under 60fps so yep ... pretty much useless on a 770 (i had a mix or AMD and nVidia GPU's over the 3 last years )

    My lowly 650 ti boost can run all games that have hardware physx (apart from Metro lol) very smoothly so your 770 should breeze it. I would sell the 580 and 770 and pop a nice 780ti in there!! :)

    Nv = Nvidia
    Very little. Don't do it unless it's another 770.

    Please combine posts. Ps NV means nvidia. Since you cant sli 5,6,7 parts together you might aswell sell off the card because there are less games utilizing physx processing...

    We live in a world of disposables, pc tech becomes obsolete within 7 years it seems now.

    Just a few days ago I put my 770 superclocked watercooled so at the moment I want to enjoy it no needed a 780 for the moment.

    as they become obsolete my first and I think that will be my last watercooling system with my forever, as a reminder of good times I had, maybe before I die i would pray that they put in the grave to cool my coffin

    and even after ... that's why you have the TPU:"Nostalgic Hardware Club" ;)

    I do,.......

    I still play UT3 and I use the two PhysX maps, Tornado & Lighthouse regularly. It's old technology, but I enjoy it still.

    Well it seems the consensus has already been laid out. As stated having dedicated physx cards have become almost obsolete especially if you already run a high end nvidia card. Very few games take advantage of physx now and the number grows smaller.

    I used to run a dedicated 550ti as a physx card but removed it due to almost no games with physx anymore and it running fine defaulted to CPU on the ones that do.

    I would say just stick with you 770 being everything, I doubt you would notice a difference with the 580 in there.

    Just last year we had AC IV Black Flag, Metro Last Light, Arkham Origins, COD Ghosts. They all utilized hardware(GPU) Physx. Its still around but is used sparingly in generally the bigger titles. I still play Mafia 2 with it turned on, Batman series, Alice, Mirrors edge and it really adds to the eye candy.

    EDIT - Also going to be used in The Witcher 3. Heres a list for you of Hardware Accelerated Physx Games

    I used a GTX650 as a PhysX card along my old (now dead) GTX570, then i sold the GTX650 and used the GTX570 alone and i notice no difference in FPS, except the PhysX effects ran faster with the GTX570, i noticed this in MetroLL and Warframe.
