Ummmm no. It's PCI-Express as I said:

In any case, I brought this G5 to my local Mac Genius Bar and the genius said that the card appears to be "incompatable" for whatever reason and suggested I buy another card. Does anyone have any good recommendation for a PCI-Express Firewire 800 card for a dual core G5?
