Do you mean to say that 8800GT die (whatever it is called...G92) will be used to release a complete range of cards from low->mid->high tier?
If so, I am wondering as to why Nvidia needs to release a higher spec card when there is absolutely no competition at high end. At low-mid range, it makes more sense because, AMD has pretty viable options in the form of HD 2900 series and the upcoming HD 38XX series.
Then again, maybe Nvidia knows something about the performance of the HD 38XX series, which scares them
We will just have to wait and see, won't we?
Good times ahead
