At a special event in PDX LAN 16.5, Nvidia previews their unreleased graphic card, yet to be named GeForce GTX 580. They claim it to be more powerful, even to be the “Fastest” DirectX 11 GPU in the market. With the new Vapor Chamber Cooling technology, it will be cooler and quiter than before.
In the video below, you can watch the previews of Call of Duty: Black Ops that runs on that unreleased graphic card. Seems interesting though.
