[QUOTE=If your sound card is PCI-E then you can put it in any of the slots as PCI-E is backwards compatible. If however, it is PCI then you will either have to use the onboard sound for 2x PCI-E x16 graphics cards, or use your PCI sound card along with 2x PCI-E GFX cards with a x8/x16 combo (could be x8/x8 I'm not sure - either way you won't notice much difference tbh but it's up to you), maybe invest in a PCI-E sound card?.[/QUOTE]

Thanks heaps for the feedback Nath.
I do appreciate your help & confirming my thoughts.
Seeing as how I sold several organs to buy all this kit I may as well get myself a new PCI-e sound card too.
Thanks again Nath.
