Well onboard realtek sound was awful. Miss my Sb x-fi now. Going to add a pci-e SB card. Can I put it in any available pci-e slot even though it has a mini 1x interface?
Yes, but if you put it into an x16 slot, or even maybe an x8 slot, make sure to doublecheck the BIOS settings. A lot of times the default is to assume anything in an x16 slot is a video card.
