M-Audio Audiophile Usb

All dabord I chose the M-Audio Audiophile USB PCI cards because with parasites often given to the powersupply too hard or bad point mass. (Ground). also for the price I had for this unit usb. I use this card to listen to music and making music through software like Cubase VST, Live 4, Fl Studio and personal registration as a digital mixer or a turntable. Here are my config below AMD Athlon XP 2600 + MSI KT4AV-L (MS-6712) Kingston 1.2GB DDR 400 memory live. Maxtor 80GB 7200rpm 8MB cache.
