The Triplehead2go is nothing more than a sort of "splitter" for VGA cables. It basically tricks your computer into thinking it is connected to a really wide monitor, so if you have 3 monitors with 1280x1024 resolution, your computer will think you have a 3840x1024 monitor and display things accordingly. It should work well enough with wow, provided your video card can handle the resolution, so if you have something high end, you should be OK (Also this is one case where SLI and multi monitors work well together.)

As long as you can get your wow windows to open up where you want them, and you can drive a very high resolution, the triplehead will work fine. Hell get 2 of em and run 6 monotirs with a regular dual head card

Downside is it doesn't work well (or at all?) with different resolution/size monitors.
