there be few manufacturer make they own version of hd 7970 , but I choose Sapphire HD 7970 OC . because it have big dual fan which be not only cool the card effectively but also very quiet . I be amaze how effective this cooling solution to the system . the other feature I like about , it have dual bio which be very good feature that you can lock in the highest clock speed . moreover , this card come with the complete accessory such as CrossFire connector , mini-dp to DVI dongle , hdmus to DVI adapter , mini-dp to dp cable , DVI to VGA adapter and 8-pin to 4-Pin Power cable . this card will stay in my system for quite a while until AMD introduce the new technology . I fully recommend this card to whom they be call as high-end gamer and Enthusiast . you will not regret .
