MacWelt.de posted benchmarks from the new Dual 1-GHz PowerMac G4 - with comparisons to older PowerMacs including the dual-800.(English Translation)
Unfortunately, they are comparing OS X 10.1.2 (Dual 1GHz) vs 10.0.4 (Dual 800).
This page shows pictures of the insides of the Dual 1-GHz.. and shows the Seagate Barracuda and GeForce4 MX. (English Translation)
Duxbury.la also posted some more realistic benchmarks (I'm assuming the same OS) between the GeForce 3 and GeForce 4MX on a Dual 1-GHz... the GeForce3 is faser... as well as some screenshots and internals.
