You have to pay for the full 3dmark key and it becomes available.
There are some SC1 and SC2 stages I can submit for, but I'm going to concentrate on SC3.
I can submit for all SC3 stages except maybe the mobile CPU one. I have a 3870X2, 2900XT 512MB and 9800 GTX+ for the GPU stages as well as the corresponding CPUs, 4 ddr2 sticks that can do 750MHz+, 2 AM2 CPUs and some Wolfdales for PiFast.
For PiFast I have 5, 7 and 8 series wolfdales so I can fill any gaps we end up with.
Also, because I have a ton of 775 chips I can just churn out submissions for dogpile.
