Linus Tech Tips (http://www.linustechtips.com/) website has performed several benchmarks to find out if low-end dedicated PhysX cards are still valuable in systems with high-end graphics cards, using Mafia 2 benchmark (http://www.youtube.com/watch?v=ONQfbGBtitY).



8600 GTS GPU is clearly bottlenecking the whole system, resulting in lower fps than even a GTX 580, despite the fact that if single NVIDIA GPU is used in Mafia II, PhysX effects are partially running on CPU (http://physxinfo.com/news/3892/mafia-ii-is-not-using-gpu-for-physx-cloth-simulation/).

GTX 550 or ‚??even something a little bit lower-end‚??, as author of this video recommends.
