News XFX unveils first overclocked GeForce 8800 GTX/GTS

I read recently that it overclocks the stream processors when you overclock the core anyway...

 

Yes, but there's no detail on how far they're overclocked in comparison to the core clock when you increase it. All that we know is that it's overclocked at the same time - I'm not sure whether it's a linear overclock or whether it's a logarithmic scale, or some other entirely different clock scaling.
