True : but the Nv 8600gts is derived from the 8800 xxxx.
Looking good for 220$.
To be confirmed !
Please be warned, i have read a review which states that basically the lower spec 8500GT, 8600GT and 8600GTS series cards are severely hobbled for features from the full 8800 series cards.
For example the number of stream processors (efectively equal to shader piplines) in each: (and frame rate in halflife2 @1280x1024)
8500GT= 16 stream processors 128bit Memory bus 24 FPS
8600GT= 32 stream processors 128bit Memory Bus 62 FPS
7900GT= 24 pixel shader units 256bit memory bus 87 FPS
8800GTS= 96 stream processors 320Bit memory bus 163 FPS
8800GTX= 128 stream processors 384Bit Memory bus 193 FPS (holy bejezus batman!!)
The review is from Atomic magazine Issue 77 (June 2007) page 50. I have just reproduced the results above.
The article was front page and called "GeForce or GeFarce". lol They seemed to think the the lower spec'd cards were being marketed as viable cheaper gaming cards when they really weren't capable of it.

I think you need to log in to read the article.
anyway from the above it would seem a 7900 is way better than the 8500, and better than the 8600.
