Anandtech has posted an absolutely scathing review of ASUS' PhysX discrete physics accelerator. Although the card seems to perform well when testing AGEIA's own demos and tests, actual gameplay benchmarking reveals that the physics "accelerator" actually yields lower framerates. Granted, this is largely due to the use of higher quality physics effects and increased data flow. However, with no way of testing this higher quality physics mode in software we have no idea whether a dual-core CPU would be able to match the PPU's performance (or lack thereof). Rest assured, we'll have that answer in the very near future as we put AGEIA's PPU to the test on the Hot Hardware workbench.
