TechReport offers a first look at the unreleased ATI Radeon HD 4850.

Quote: "The battle between AMD and Nvidia for the hearts, minds, and disposable income of PC enthusiasts is starting to get scrappy. First, AMD scheduled a press event to distract folks from Nvidia's GeForce GTX 200 series launch, which Nvidia subsequently pulled forward.
