Is it worth doing if I just have an extra card lying around? I'm getting a 980 and my 560ti will just be sitting around.

not worth it. The 980 will do both no problem.

What exactly is a physx card and how does it work? I have heard that it works with 2 GPU's that don't have the same chips in them. From what I have heard you could have a main card running graphics and another card calculating physx effects? Sorry for a noob question. Heck this might not even exsist.

It's just like that.

The only reason to do that in the first place was if you had an AMD card but now it work work anyway unless your main card is Nvidia.

If it were me with another card just laying around, I'd probably mess around with it and see what kind of performance difference (if any) I can find in PhysX-heavy games. No, you definitely don't need a dedicated PhysX card, but why not tinker when you've got the opportunity? Might be fun.

 

Beware that many power supplies may have some difficulty powering both cards unless designed for multiple GPUs. You'll need four PCIe power connectors (6- and/or 8-pin, no idea what they need) and a fairly robust continuous wattage. If there's any doubt, or if you need to use cable adapters or something, just skip it. On a side note, amusingly, the GTX 560 Ti probably draws a bit more power than the 980.

While it's not a 560ti that is mainly looked at in this article, their data definitely disagrees with the notion that adding a dedicated physx card to a high end main GPU--the 780ti in this case--isn't necessary. If you have it lying around anyway, and your power supply can handle both, then you should definitely toss it in there. Give it a read and decide for yourself, though.
