ATI has announced their new product, the RAGE Fury MAXX, a dual processor, 64MB card (thanks Redwood). The card is expected to ship, "in the fourth quarter" and retail for about $299. Here's an excerpt from the press release:

Superior to single chip solutions, ATI's MAXX technique achieves maximum efficiency by having each graphics chip render alternate frames, cutting the rendering load in half. With the two chip setup, one chip renders even frames only while the other renders odd frames only. Each chip performs triangle setup for its own frame without having to wait for the other chip. Since the complexity of a scene tends to vary only slightly from frame to frame (unlike the complexity of different parts of each frame, which can vary widely), the load between the graphics chips tends to stay well balanced. Also, because each chip has its own dedicated frame buffer space in local graphics memory, the final image is buffered to prevent any tearing, discontinuity, or other artifacts.
