I wrote an article for the upcoming book ShaderX 2 about some GPU based
linear algebra solvers, including an LCP solver (which is what you need to
do constrained rigid body simulation).  These run on any graphics card with
decent DirectX 9 support, and I clocked them to be competitive with or
faster than SSE2 optimized CPU code.  There is also a paper coming in
Siggraph 2003 about sparse solvers, which are even more interesting.  So
clearly, it is not neccesary to create yet another piece of specialized
hardware for the PC -- with GPUs you already have/will have powerful,
general purpose floating point vector processors.
