Regarding multiple external displays, the display port 1.2  standard
supports 'multi-stream'.
This means that some monitors allow 'daisy-chaining', and there are also
monitor hubs available [1],
so there is no 1:1 mapping between ports and monitors.

Of-course your graphics card has to support it, and the bandwidth is
limited (up to 4 1080p displays for example)[2],
and Shachar's comments about GPU memory and capabilities are correct,
but it should work  (in Linux kernels >= 3.17 )
