I was wondering if it's possible to get a dual port video card for my G3 iMac (built just before the G4 iMacs came out) so I can use external monitors with it. For the past 4 years I've used a Matrox G450 dual port video card on my Windows box. I would like to switch over to just using Mac and would like the bigger screen area. Does anybody know if this is possible? If so, what video card would I need and how much do they cost? I just can't get used to using that tiny screen when I'm used to using dual 19" monitors.
