What GPU you use as your primary one? Anyways dedicated physx card is just useless as it gives little to no gain, or even decline performance if u use a very old card, or a very old connection for physx as they can bottleneck your primary GPU. Watch the video on physx in 2016 from Linus tech tips.

 

To your question now, pci-e 3.0 4x is essentially the same bandwidth as pci-e 2.0 8x. So you should be fine with whatever you want to do, though it's gonna be useless and just consume more power
