Built my new system today. Installed the Drivers for my GTX 580 off the CD that came with the box. I now want to update my drivers from the EVGA website and I just want to make sure I am doing it right since I'm no longer using XP, but Win 7.
From the CD I was able to install the Drivers, 3D Vision, HD Audio, PhysX System, EVGA Precision. (not sure what the PhysX is)
Nvidia have recently updated their installer. Grab the latest driver from geforce.com and just run the installation. It will give you the option to upgrade the existing driver or perform a clean installation.
