I have a G4 500 MHz AGP based power mac with a ATI Rage Pro graphics card in it. Will an AGP graphics card from a newer Dual processor G4 work in my computer. The newer card is an ATI Radeon OEM edition. I have talked to my local apple consultant and he said it should work but with out the ADC connector functioning completely . Does anyone know by experience if it will work for sure. Thank you, Dan Brieck Jr.
