you have to look at the mb guild. most new mb will let you turn on two ports. the dvi and hdmi or the dvi and vga ports. it be in the mb guild. on video cards you want to buy the newer 6xx or amd cards as they use less power then the used 250.
Simple. Install drivers, connect second monitor to next available port and configure in Windows control panel.
As you can see the board just have one video output.
But guess a splitter like I've linked to is useable
