Your benchmarks apply to GPU-accelerated PhysX, not the PhysX engine or PhysX processing. GPU-accelerated PhysX is an exceptionally rare feature that has been used by less than 20 PC games. Such games include Mirror's Edge, Mafia II, and Metro 2033. Planetside 2 will almost certainly not be using this type of PhysX.
Exactly, this is worth noting. PhysX can do regular physics processing of rigid bodies, basic ballistics and things like this with relative ease, you don't need a very fast PC to process these types of physics effects since they're not very complicated calculations.

There's a newer set of special effects which include things like pseudo-cloth and pseudo-liquid physics which are too complex for the CPU to deal with in real time rendering and can be passed off to the GPU for calculation, Planetside 2 will probably not use these effects.

These effects are really just that, they're graphical effects designed to increase eye candy and like most other graphics effects they can be turned off, much like you could turn off grass in Planetside 1. They're not actually relevant to the game logic, for example getting submerged in pseudo-liquid is not going to drown you, and a flag made out of pseudo-cloth is not going to block the line of sight of AI.
