nowadays i only ever use 1 pci slot... for my audigy... i built 6 comps last week, 5 for my dads office and 1 for my bro and they use a total of 0 PCI slots between them... nowadays with mobos having so many USB outlets & hi-quality onboard sound its hard to use more than 1 or 2 pci slots unless you have a tv tuner card or something... its only a matter of time till those are pciE anyway... 🙂
