There are always many different "manufacturers" of graphics cards. ASUS, Gigabyte, HIS, Powercolor...etc. Most of the time they look a bit different, design and sticker wise. I really wonder why the "Apple Certiifed" Version of the 5870 (with a nice additional metal backplate and 2 display port ports, instea dof HDMI) goes for 3 times the money on ebay as the "normal" versions ? Is it really just this additional "metal plate" (and 2 display port ports, instead of HDMI) ? (and that it has the apple word in it ?) Or is there more to it ? Firmware related maybe ? Completely different PCB ? I cant seem to find an "apple logo" on the card for example. And there are indeed "apple certified" cards with NO display port ports on it : The only obvious difference here seems to be the texture of the black plastic cover... Id love to know more.
