AS NVIDIA'S VICE PRESIDENT OF Technical Marketing, Tony Tamasi is more than just a marketing guy. He listens to customer feedback, helps define product specs, and then once the products are ready to roll, he acts as NVIDIA's liaison and chief technical evangelist to the rest of the world. As you might imagine, he's had his hands full with the launch of the GeForce 6 series of GPUs, but he was kind enough to take time and answer some of our questions about NVIDIA's impressive new graphics processors. Among the subjects discussed are pricing and availability for the GeForce 6800 family, the uses of Shader Model 3.0 for real-time apps and games, the NV40 architecture, and some intriguing clarifications about those Far Cry screenshots that recently hit the web.
