Mobo: http://www.newegg.com/Product/Product.aspx?Item=N82E16813130098

RAM:http://www.newegg.com/Product/Product.aspx?Item=N82E16820231098

PSU:http://www.newegg.com/Product/Product.aspx?Item=N82E16817104934

650W PSU will be overkill, a good brand 500W PSU will be ok for that 8800GTS 320mb (there are not GTX 320mb as you write)
