I recently upgraded to a MSI GeForce GTX 660 N660 Gaming 2GD5/OC Video card and was wondering if my computer had the capability to have dual monitors. I am not quite sure how it works but I have seen people have monitors next to each other and could make the mouse go from one screen to the other and have two things up at once. I was also wondering what downsides the dual monitors could have with my build.
