I am adding a second card to my DP867. I'll run the main monitor off my stock AGP card so I need a PCI card to run the TV (for video stuff). I want one that can run the tv as a second monitor, not a mirror of the desktop. This is so I can preview effects/movies/titles as they will appear on a TV and not the monitor (big difference!). I'm leaning towards a 32MB ATI card since they seem to be fairly easy to find. Any other mac cards I should look at? Do I need the Mac card or can I get any old PCI card and download drivers? Oh, S-video or composite (prefered).
