What does this mean? If you already own the 8800GTS 640mb graphics card, you will be aware it has 96 stream processors, the 8800GTX has 128, 32 more giving the GTX around a 20-30fps boost.
New 8800GTS 640mb cards will be made on a revised SKU - 0008, which has 112 stream processors, 16 more which is likely to result in a 10-15fps boost over existing 8800GTS 640mb models.
It would seem the 8800GTS 320mb will become EOL (End Of Line) replaced by the improved 8800GT and new 8800GTS 640mb performance will lie exactly between current 8800GTS 640mb and 8800GTX cards.
