I have an AN7 from ABIT, that dosent really matter. What i want to know is there a difference between the performance of PCI slots? Is the closest to AGP faster or better for soundcards? I have an SB Audigy 2 ZS and i get glitches in the sound sometimes and in some games only. I was wondering if maybe it was the slot or just a bug between these games and SB Audigy2.
