To make use of a second card and SLI it with your first it will have to be another GTX 470. Do what I did with my 470, just buy an EVGA UV Plus.
Doing SLI will defeat the purpose, as the goal is to run 3 monitors. SLI will only allow 2 monitors.
Abik, I have a question: are you planning on gaming on 3 monitors? I don;t think that's possible with NVIDIA cards. But if all you need is to stretch your desktop, then any 2 cards will do that.
