That one might just about do it for HTPC use if you ensure good ambient airflow (assuming the RAM can be left out of the heatsink's budget), but would probably still throttle badly under gaming loads. Mounting it to the board is yet another issue; being copper, the weight is probably too much for adhesive TIM, and it may not be shaped right to clear other components on the board.
That might be thermally excellent with ductwork such that a case fan is forcing air through it, if you don't mind fabricating such things and don't mind the card's cooling system not really being self-contained.
