OCC has published a review on the Sapphire HD 6850 Toxic video card

The Toxic Edition video cards from Sapphire have always had that extra something special that sets them apart from the crowd. That something is usually a deviation from the reference design, which includes PCB improvements as well as better component and cooling selections. Add to that the increased clock speeds and you have a card that provides performance above that of its AMD competitor's reference designs. That really is the goal with a factory overclocked video card anyways, now isn't it?
