Actually, I believe that the G70 is for 7800 ***. The NV47.
Funny, remember how much press and excitement there was about the NV40? I mean, there was a ton, I must've read so many articles on it (and I know others did, too) that the word count probably surpassed that of the Bible.
So, that said, it is in my mind that this is a preview of something that NVIDIA is planning, which will be much, much better and faster, etc.
