Benchmark Reviews published a report about the new NVIDIA GTX 200.

Quote: "Hot on the heels of a rapid-succession GeForce 9800 GX2 and GeForce 9800 GTX launch only two short months ago, NVIDIA now officially unveils the GeForce GTX 280 and GTX 260 video cards. Using the fastest and most-powerful graphics processor NVIDIA has ever developed, both new GeForce products are constructed from a freshly-minted GT200 graphics processor. Both the GTX 280 and GTX 260 products position themselves at the very highest segment of the GeForce product line.
NVIDIA Estimates that the GeForce GTX 280 will be introduced at $649, while the similarly powerful GeForce GTX 260 will enter the $399 price point. If the competition ever had a very good reason to be concerned with their future, it would be right now. "
