I just bought this http://www.newegg.com/Product/Product.aspx?Item=N82E16829132010 <><> and since it does not have standard 7.1 connectors what will I need to buy to set it up as 7.1 configuration.I have 5.1 speakers and I have a few extra speakers laying around in the garage that are still usable. Next week I am buying this receiver <><> http://www.newegg.com/Product/Product.aspx?Item=N82E16882117343<><> For better sound quality am I supposed to connect the receiver to the sound card somehow ??
