I know one is PCI and one is PCIex1 but what's the difference in Audio quality?
ALso how do these Sound cards compare in quality to something like Asus's generic Motherboard Realtek® ALC887 8-Channel High Definition Audio CODEC such as on a B85 Plus?
Also how do they compare to Asus's SupremeFX 8-Channel High Definition Audio CODEC on their B85 PRO GAMER?
