[davoftw]

So i've just bought this:

Inb4 horrible setup etc, just need it for streaming Runescape & league of legends

Would like to know what needs to be done to be able to use 3 monitors please.

In example; would a new graphics card (Around the $120-150 AUD mark) do it for me?

Also they would all be 21.5inch and have DVI and VGA inputs
