Dedicated PhysX card

Does the card use its total tdp all the time since its only doing the calculations for PhysX?

More than likely no, unless it's being pushed to near 100% usage. 

 

They're useless btw, don't bother.

Not worth it, a 780 can handle physx fine with very little performance decrease

After extensive benchmarking with and without physx with multiple systems in different price ranges and gpu's the physx card is literally useless, the system that showed this the best was actually my sig system. we used a gtx 770 as a physx so its guaranteed there wouldnt be any kind of issues with a physx card bottlenecking the main gpu's and at the most we saw a 5 fps gain. on average though it was no gain at all and some games even LOST frame rate because of the dedicated physx

This is true, I once used a GTX 660 in my PC as a dedicated PhysX Card
