HI I'm re-playing metro 2033 but this time on hard, I have a FX-6100 and a 560gtx, when playing Metro which would get me the best performance, running Phys-X on the cpu or the gpu. I have 8gb of ddr3 1600mhz ram, and my resolution is 1440x900. Thank you

PhysX is severely crippled on the CPU, GPU give the best results BUT unfortunately Metro is pretty demanding and adding PhysX is gonna make it perform worse...
amd improved a lot in the field of physx with their fx-series,the fx-6100 would be decent enough but the gtx560 would be much much better. i'd say to turn both on by the auto select option and it will intelligently use both
