Speaking of sound in the Mac Pro...would buying a PCI(E) sound card work in a mac pro. I am talking about using it just in Windows for 5.1 sound. Something like this.

Also, if this works would PCI or PCIe be the way to go?
I thought when you install the drivers from the MacOS CD in Windows you get 5.1 through the optical? I am pretty sure that's how mine is right now. Don't need the card?
