now u see the reason for that is ur dedicated card is AMD (ie no support for nVidia's proprietary physx software). Thus, your system is trying to load physx (parallel computing optimized API) to the CPU which is better suited at serial computing! It's kinda like trying to get a CPU to render graphics to a lesser degree...basically hopeless to run physx without a compatible GPU! now if your main GPU was nVidia and u did the benchmark comparing with and without dedicated GT430 physx computing then it would be more of a real world interest to this, and I presume then the effect would be negligible or even detrimental if the main GPU is far more powerful than the dedicated physx card (in such a situation the physx card would be the bottleneck).
