I use triple monitors. Two 22" side by side for the main view and another one above my keyboards as I can't be bothered to turn my head anymore.
I really want to do that as well. currently my video card only supports 2 monitors, but I would love to add another so I can put a screen in front of my keyboards.
If you already have the monitor the expense isn't that great. I have two ATI 5450 cards. One is in the PCIe x16 slot, the other in one of the x8 slots (IIRC).
You will need two cards that can use the same driver though. I tried it with two different cards and it was a nightmare although there are some on the web claim it can be done I never got it working, not under windows 7. It seems to me that XP actually had better support for two graphics cards as I ran two different ones under that OS.
My MB supports crossfire natively but I believe the cards can be linked with a cable if your MB doesn't. Crossfire is the ATi term I have no idea what NVidea call theirs.
It's a nice luxury but I still haven't found any way of extending a desktop across two and cloning the desktop onto the other one. There are workarounds and I'm using DisplayFusionPro which can mirror a monitor or window to the third one but to be honest it's a bit kludgey. I trialled one of the other alternatives and it wasn't much better.
Now I just have a keyboard shortcut set up to switch windows between monitors so just do that as required. It is a handy extravagance though.
