Excerpt: Much hay has been made of the incredible speed advantages PCI Express offers over PCI. Beyond GPUs, however, we haven’t found much worthy of occupying those slots. Asus hopes to change that with its Xonar D2X card—the first soundcard we’ve reviewed that makes use of the PCI Express interface. The D2X is basically a PCI-E version of the Xonar D2 (reviewed April 2008).
Pros: The EAX 5 hack is commendable and the card’s LED lights add flash.
Cons: Initially spotty PCI-E support that must be fixed with a BIOS update.
