Summary: This card makes a beautiful sound, combined with the 5.1 speaker system I bought at the same time ... sometimes. Unfortunately I've had repeated problems with it either making a horrible noise or none at all.
Summary: Great sound when you can finally get it to work. Latency is a major problem with these cards. Asus/cmedia xonar drivers are terrible and written by complete amateurs. Asus just don't seem to care that the product is really let down by the drivers.
Summary: I was looking for a card with DTS Connect for watching movies. As this card also boasts ASIO 2 I thought I was on to a winner. While the new drivers in XP will bring down latency for playback in Cubase SX3, monitoring (which is what ASIO is all about) is completely broken.
