Some images have surfaced of the NVIDIA 9800 GTX and according to the notes on the page with them, the 9800 GTX will be a G92-based product and will basically be a higher clocked 8800 GT/GTS card.  Not a whole lot more data, but if you wanna see what a video card looks like, I guess you can look here; not much to see.
