Second graphics card for dual display

[fr]

I am planning on getting a dual display setup. Right now I'm running W2K SP2 with an AGP GF2 MX and a Optiquest V95 monitor. Would I be better off getting a new video card that supports dual display built-in or would I be OK just getting a separate PCI graphics card for the second monitor? I would appreciate any suggestions on which card to get.
