hello. i have the asus maximux v gene motherboard, which comes with the supreme fx III chip on it, and the sound blaster x-fi MB 2 codec/software. i also have a creative x-fi titanium sound card. i believe its the older model, but is still pci-e x1. im wondering which should i use for my sound. it will be hooked up to a home audio reciever through an optical cable. any opinions would be great. thanks
