3 HDMI Connections 2013+ Mac Pro

So – you’re trying to dongle your way to 3 monitor goodness?  Just a quick heads up – you cant have 3 HDMI based monitors connected to your fancy little trash can (Mac Pro).  The systems only support 2 HDMI headers.  You can have a 3rd (maybe even a 4th?) monitor connected but that have to be DVI or VGA.  2HDMI+1/2 VGA/DVI’s should work fine though.
