[Pc_Support] AnandTech has a silent GPU round-up ...

[Bryan J. Smith]

Largely 7300GS/GTs, 7600GSes, a few 7600GTs and even one 7800GT:

Note that the combo-front/back passive heatsinks on the 7600GT and
7800GT solution could take up to 3 slots!

I'm going to be updating my blog article with this info, as well as
the new 7100GS, 7900GS and 7950GT shortly ...

Especially since I'm putting my wife's 7900GS this weekend.  I'm still
wondering if the GPU/mem clocks are at 375/1000 or possibly the
450/1320 -- and what (inadequate?) cooling they are using.
