NVidia PhysX Integration

while trying to create advanced ragdoll physics i found that my physics engine isn't so stable.
for example: if i throw ragdoll from high place to the ground, it could get very unstable due to my simple solver.
as you all know, nvidia acquired ageia physx and they also have 2 new cards geforce 260/280 thats have build in physics accelerator. (based on ageia physx technologies)
i think is great solution, buying one card that support graphics and physics is cool.
the solution to my physics problems was very simple:
1. i could spend few more weeks to fix and some few other things on the way
2. integrate some of the commercial physics libs. (havok/physx)
i decided that it is best to go with option 2.
another question was havok or physx? i decided to go with physx as it is very understandable, easy and have tons of samples.
the integration went very smooth, i change my physics manager to support their function and the ragdoll is very stable now.
