I investigated more on one of the issues i reported in my previuosly msg, I don't know why but System Profiler reports only one core (my CPU is an AMD X2 4200+) but Activity Monitor shows two cores working so I think it's only a bug in the program that try to identify the CPU.

I will investigate more on the GPU issue now, because I noticed that it's not related to NVinject.kext, if I copy only that one from my previuosly installation I still have a lot of graphics artifacts and no CI/QE, if I copy all the old kext related to graphics (Geforce.kext and all the others) everything works fine exept the graphic memory size reported by System profiler (771MB and not 512MB) ...

Great work Zephyroth with this release!!
