I would like to setup three or four monitors on my computer. I want the screens to have individual properties but also be connected in a panoramic fashion. Can I add more video cards or should I get a ready made unit that supports several monitors? If so, where's a good place to look for one?

I tried building my own multi-monitor computer but I got a lot of crashes etc. I finally broke down and bought a really nice SUPER PC™ Quad Monitor system and it runs great. Check out Multi-Monitors.com. They pretty much have every way you can think of to configure multiple monitors.

Better you buy a multi-monitor system. that will be more durable.
