    I have a 980ti that I am using but have an older gtx 570 laying around. Would it be worth the trouble in putting the 570 in my gaming rig to use as a separate physics engine ? Would I even notice it ?

    Depends on a few factors.

    The main factor being, does the game even support GPU accelerated PhysX
    This list gives you an idea,
    http://www.geforce.com/hardware/technology/physx/games
    But, keep in mind some of the games on that list are locked to only run on the CPU (and it's already a rather small list).

    The second thing to keep in mind is, assuming the game actually is supported, how well do you run the game already? If you already have 100 FPS, do you desire more for that specific game?
    And if so, the last factor comes to mind, do you want to bother with the extra space, power, and heat another GPU causes.

    If so, then I say give it a go...

    I did some test awhile back with Physx card.Maybe this can help you decide.
    Though Physx aint really a thing anymore like Cyberdyne posted.

    Interesting.. Thanks for the input.. Looks to be not really worth the hassle for a few extra frames when a 980ti eats everything up at 1080p anyway...

    Exactly. To start seeing some real gains you need pretty up to date physx cards, and with older stuff you usally can't win much.

    Meh, I did it before with a GTX 750 Ti, saw almost no gains. IMHO it isn't worth it.
