In my old agp mobo the manual gave a list of which pci slots shared interupts such that you could ensure the graphics card would not share an IRQ with the sound card. I've just finished setting up my DFI lan party nf4 ultra-d and currently have the audigy in the bottom most pci slot, with 8800gtx in the top most big pci-e slot. I'm getting the odd click here and there and have had one sound loop lock up in Fear after a few hours play. So I was wondering if the pci/irq sharing thing applied to a pci-e mobo and if so which slots share with which, can't seem to find this info in the manual.
