I looked at pictures of the Gigabyte P35-DS4 version 1.0 and it looks identical to the P35-DQ6 version 1.0. When I bought my DQ6 the DS4 wasn't available in the USA. The DS4 revision 2.0 doesn't have the serial and printer connectors and has more USB ports. But considering the price difference between the DQ6 and the DS4 (revision 2) of $72 at Newegg, the DS4 seems to be the one to buy now. I now understand why Gigabyte discontinued the P35-DQ6. It seems to be the same board as the DS4!
