Its my understanding that Sapphire is a subsidiary of PC Partner, a large Taiwan Holding company. PC Partner has built the majority of ALL ATI cards including OEMs for the last several years and started up Sapphire recently as an outlet for their own branded cards. So Sapphire and ATI cards may not be the same card even if they are produced by the same manufacturer.
Also, both the RAMDACs on 9xxx are internal, so the DVI-I/ DVI-D nonesense of some 8500 cards should no longer be true. All Radeon 9xxx DVI are now DVI-I.
