Need an Nvidia GPU that supports 3 monitors simultaneously

Solution
The 750 or 750Ti will do it, for relatively low power too, at ~$150. Depending on how you intend to hook them up though, you may need a couple conversion adapters. Most have a variety combination of DisplayPort, HDMI, DVI, or VGA, so make sure to look at product photos and figure out which has the most connectors you'll need.

A GT 640 will do it as well, and those are sub $100
