Investor's Business Daily has posted this article detailing the NV30, officially dubbed the GeForce FX. Aside from the name, the only piece of information that hasn't been mentioned many times before is the price, which will be $360 according to the article, presumably to better compete with the Radeon 9700. Here's a blurb:
The GeForce FX chips are set to go on sale in February. Gaming enthusiasts will be able to buy a graphics card with a GeForce FX chip for about $360, Nvidia officials say. They also say some workstation and PC makers plan to include the chips in new machines, including Fujitsu Siemens Computers.
