Hi Aubrey Granner-
The ATI Radeon 9000 is a better card than the Geforce4 MX.

Another good thing about ATI cards is the native drivers in OS X are better than the Nvidia drivers. The
ATI Displays Control Panel is also nice for configuring the Radeon cards, and help when connected to TV's because of overscan control ability.
All DVI equipped OEM cards have DVI-I. As I said, this is both analog and digital, so analog (VGA) adapters may be used.
DVI-D is digital only.
DVI-A is analog only.
With the 9000, you will be able to use the ADC port for your monitor, and use DVI to VGA or DVI to HDMI to the TV.
Again, if at all possible, stick with a digital connection (DVI to HDMI) to the TV.
