Windows XP supports multiple monitors.
One card PCI or AGP.
Cards can be had for less then 70 dollars. Graphic
processors are built in so very low load
on cpu.
No overkill.
Once you try it you will never go back.
The inexpensive N-vida card allows you to rotate your LCD screens
90 degrees so you can work on two full page documents
in different programs at once.

Did you see the card I use from post 88? :-)
