AcousticPC has sent me over the Thermalright True Copper Ultra-120 Extreme CPU Heatsink - Limited Edition, or TRUE Copper for review. This thing is huge, coming in at 1900Grams or about 4lbs, it's enough to bust some motherboards, but if your board can handle it then get it as it will provide the best cooling performance of any air cooled CPU cooler on the market today, and most likely in the foreseeable future as well.
