Are there any difference between the sapphire OC 7850 and regular 7850? Like maybe the fans or coolers or heatsinks? there is no more OC 7850 in stock anywhere, please help, should I just purchase the regular one? and should I buy Sapphire over gigabyte or asus? any suggestions please!
Also if these video cards have 1x HDMI port how can I use hdmi on both screens!
