Had with an older motherboard that still has PCI slots, replace the internal sound processor and have decided after a long search for it here. Installs itself properly under XP and W7. One need only be patient until the automatic installation routine has downloaded and installed the correct driver. With the drivers located on the included CD I did not even try, because the always want to update the same from the Internet after installing anyway. So why not equal the initial installation directly from the Internet?
Excellent sound, everything I expect from a sound card, so 5 star without compromising.
