Actually it depends "how new", but since the dual processor had a Radeon
card, it's probably a "Gigabit Ethernet" G4, which is very similar to the
G4/500 "AGP Graphics". Both have 2x AGP slots, as opposed to the 4x slots on
newer G4's. 

The ADC connector should work fine; what the tech may have been referring to
is the ability to use BOTH the ADC and VGA connectors at the same time to
drive 2 monitors (you can't do this). IIRC, the only AGP card that lets you
drive 2 monitors at the same time on the G4 AGP Graphics is the Radeon 8500.

Also, you will probably get less performance with Quartz Extreme with the 2x
AGP slot vs. a 4x AGP slot.

I believe David may have been referring to "PCI" (rather than "ATI") in his
reply.
