The Ageia PhysX SDK is indeed interesting, but at the moment it is closed 
source. My opinion on the big benefits of open source are from the 
perspective from an co-author trying to get developers using a free open 
source library :) 

With respect to hardware, I believe in the power of Playstation 3 CELL, 
multi-core and GPU. For example, the NVidia 8800 GPU can run 15000 rigid 
bodies in about 130 FPS, and also run SPH fluid simulation at about 70 FPS: 


PS: those opinions are just mine, not my employer
