Hi everyone. I'm looking to upgrade either a Digital Audio, Quicksilver, or Mirrored Drive Door PowerMac G4. I've got everything decided except the video card. I've stumbled upon a really good deal on a Radeon 9800 Pro. Given that it has an ADC port I'm assuming that it's out of a PowerMac G5. Is it possible to put this card in a G4? Thanks.

As Erik pointed out, there is one pin that cannot come in contact with the G4 or else it will fail to work. Said pin is the G4'd ADC pin spot iirc.
