Maybe you misunderstood me (I may not have been perfectly clear in my statement), the ATI Radeon 9200 will work in a PCI or PCI-X slot in a G5 Power Mac . So if you have an empty PCI or PCI-X slot, the ATI Radeon 9200 will work in that slot to give you another 2 displays. Although it isn't a PCI-X card PCI-X slots are backwards compatible with newer PCI cards.
