Sapphire Atomic Radeon HD4870 X2 2048MB Graphics Card Review
 

The features, specifications, real world performance, and physical appearance of the Sapphire Atomic Radeon HD4870 X2 2048MB graphics card are all incredible. It is one of the highest performance cards on the market, while also probably being one of the coolest and quietest. This low noise and low heat is even more impressive when you consider that it isn't just the GPU being cooled, but the CPU and the case, too. http://www.bigbruin.com/2008/atomic4870x2_1
