From the latest Forceware 158.16, NVIDIA has at least four new G80 chips we haven't seen before. The first one is G80-400, then there is a G80-200 chip and finally G80-600 is listed. Last but not least the mystical Geforce 8800 Ultra makes an appearance.

The most important one is the new card ID // 0194, which is called NVIDIA Geforce 8800 Ultra. This new driver should really boost the performance of all G8X parts.

Here are the new cards.
// 0190 - NVIDIA G80-400
// 0191 - NVIDIA GeForce 8800 GTX
// 0192 - NVIDIA G80-200
// 0193 - NVIDIA GeForce 8800 GTS
// 0194 - NVIDIA GeForce 8800 Ultra
// 0197 - NVIDIA G80-600
