[WBB]

Hello, is the Creative Sound Blaster X-Fi XtremeMusic combatible with my ASUS P5GD1 motherboard?
(http://www.asus.com/products.aspx?l1=3&l2=11&l3=24&model=163&modelmenu=1))

It says that the soundcard needs a free PCI 2.1-port on the motherboard, but im not shure that the port on my motherboard is PCI 2.1?
