Get a little more with the ThermalTake TMG AT2, reviewed by techPowerUp!.  While the performance gains may not be huge, dropping the fan noise from 65 to 51 dbA may be music to your ears.
“The Thermaltake TMG AT2 is a cooler for ATI’s Radeon X1800, X1900 and X1950 Series. It uses a combination of copper and aluminum to optimize the cooling. We compared the cooler to the Arctic Cooling Accelero X2 and the Zalman FC-ZV9 Fatal1ty. The temperature results were among the best of the tested coolers. Not only performance is great, but the installation is also very easy to perform, in just a couple of minutes.”
