Thanks for both of your responses. I just bought what was said to be a RADEON 9000 PRO MAC EDITION, but it has VGA, DVI, & video connectors. It does not work in my Mac but does in my PC. Also my GeForce2 MX has an extra little tab in front of the AGP connector that this card does not. Is that tab for the ADC connector and do all Mac cards have that?
