This is what I use:

- https://askubuntu.com/questions/61396/how-do-i-install-the-nvidia-drivers

It's currently losing the google juice to this question though: https://askubuntu.com/questions/451221/how-do-i-install-the-nvidia-driver-for-a-geforce-gt-630

Maybe we should consider a merge? Also I'm wondering if trimming down the accepted answer would help, it's almost too overwhelming!
