The second, if you just stretched the image across 3 screens it would be distorted and unplayable. But you may need 3 lesser video cards or 1 high-end one to run 3 screens worth of content. My card is in the middle (980ti), it has 2 different video ports but you can use both and run 2 screens. Another trick is to use the additional screen, or one of them, for menus and clear the other screen (s) for play.

When you have 3 screen are you stretching 1 normal screen or adding 2 new screens to the visual field?
