The quick answer to which Radeon Video Cards support three monitors is any card with the ALL THREE of the following characteristics:

  1. The Radeon card has three heads/outputs (like VGA, DVI, DisplayPort, HDMI…)
  2. At least ONE of those heads is Display Port
  3. It has the EYEFINITY branding

Eyefinity is the AMD/ATI marketing term which means that card can support between 3 to 6 monitors (yes, you can buy Radeon cards that support SIX monitors).  For more details see THIS AMD link and as of March 2014 see the table below for the current product list.

Did you know that in addition to the typical way to get three displays (using all three heads), you can run THREE monitors from just ONE  DisplayPort head using ATI’s new MST technology:

For many technological reasons (PDF), DisplayPort is also a superior alternative to the same old connections (HDMI, VGA, DVI) that we’ve been using for a long time. For example, DisplayPort can deliver stereoscopic 3D content—like 3D games or Blu-ray—but at a much higher resolution and frame rate than either DVI or HDMI can provide. As another example, AMD products that feature DisplayPort 1.2 outputs can actually run several displays from just one port. This feature requires specialized display hubs (available 2012), but DVI and HDMI can’t do that!

URTECH.CA: You can buy an (Multi-Stream Transport) MST Hub / DisplayPort Hub HERE or HERE for about $125 .
