The instructions now are to go to the restricted driver manager and enable the video driver, ie. System-> Administration->Restricted Devices Manager, Enable Driver, Apply Changes.
The instructions you got (to go to the nVidia website) were not the official ones. Ubuntu has (as far as I can remember) always had nVidia's binary drivers in their repositories. Getting them from nVidia generally involves a bit more work and makes upgrades (eg. kernel) more difficult.
