Game on 3 monitors

[Snipedubad]

I was wondering on how to make my game go on all three monitors.
Do I need two GPU'S to do it?

specs:
Motherboard: Sabertooth Z87
GPU: GTX 770

One GPU should do 3 screens at low-med settings. Set it up and see how well it works for you. Go to Control Panel->Nvidia Control Panel and set up Nvidia Surround via the link on the left.
