A (Chinese) message board user has posted several pictures of what is claimed to be NVIDIA's next-generation G80 (DX10 compatible) graphics card. Latest reports suggest there will be two models, the GeForce 8800 GTX ($649 USD) and the GeForce 8800 GT ($449-499 USD). The GTX version (higher-end) will feature a 384-bit memory interface, a hybrid water and air cooler and 7 TCPs, while the GT will have a 320-bit memory interface, a standard air cooler, and 6 TCPs.
