I am thinking of getting a dual G5 2GHZ with the PCI slots. I have heard of some problems with both the PCI slots (m-audio, TC powercore) and some problems with the PCI-X slots with incompatibility. I plan to use a Multiface in conjunction with a Fireface through core audio. Can people please tell me their experiences with either of the Dual Macs and let me know if I can expect any problems. Thanks in Advance.
