hi Alessandro, one question: did you do a reboot after installing this driver?? Normally, it is necessary to reboot the system after installation to get this driver into action.
You also can test the successfull installation with the instruction here: http://askubuntu.com/questions/37084/nvidia-driver-activated-but- currently-not-in-use With this instruction, you will see, that your driver is in use after rebooting your system. And you also notice the successfull installation through an immediate downdrop of your GPU-temperature and the icon for the GPU in your panel (if you have sensors-applet in your panel) also changes to the correct one.
