Ran the test @ 1600x1200/1280x1024 (dual screen) max settings on firstname.lastname@example.org/7900gt/2gb ram/raptor75gig: 103.3 score
My Core Duo 1.8ghz 1gig of ram and a x1600 mobile got a 157.1 on the supcom stress test.
So you have double the cpu, graphics, ram, and hd and you went down 50 points.
Granted it's better, but it's hard to decipher which is the more important component.
Can anyone post some more scores?
