Tutorial for setting up a Linux machine with 3 monitors? [closed]

Can you provide a link to an up-to-date tutorial for setting up Linux with 3 monitors? Specifically, I want to set up 2 different nvidia video cards with 3 monitors. I can already do 2 monitors on 1 video card, so I am not interested in those tutorials.
