Multimple Monitors

[gm@xxxxxxxxxxxxx (Gerald Marisch)]

I have a Dell Pentium II with Win98.  I'm now running 2 monitors after
installing an ATI Rage Pro video card.

I would like to run a third monitor.  I have heard of cards with multiply
ports for multiple monitors.

Any suggestions / ideas what's involved, a recommendation for a card (a 2nd
single video card or a multi-port video card) installing and setup, etc.?

Thanks for any input.
