Hardware that I use:

Matrox's triple head 2 go.

Prior to starting to multi-box I ran wow across 3 screens, and this device is absolutely perfect! (well, i wish it did 1600x1200 x 3).

Now that I have started to multi, I can run 3 wows on seperate screens without a problem.

The software that comes with the hardware, tells Windows you have 1 monitor attached instead of 3 (at 3840x1024) = 1280x1024 x 3.

I am considering getting another one since my video card has two dvi outputs and seeing if I can run 6 monitors (with the OS only showing 2).

I found my Matrox from another website for under 300 bucks, so not bad for the ability to play across multiple screens or run 3 wow's on each.

(for those of you who opt to MBox w/software and not hardware)
