"This reference design by HIS concentrates on the cooling system replacement in order to push the card at its maximum. The card is 7 to 10 degrees cooler than the reference board and in the same time is overclocked (840MHz instead of 800MHz for the GPU and 1280MHz instead of 1250MHz for the memory). The performances are almost the same than the Sapphire board and you are also able to overclock it a little bit more. This card uses only a few watts more than the Sapphire board."
