New evidence proves processor speed is most important choice for Civil 3D performance

I ran some tests on Civil 3d 2011.  Here are the system configuration comparisons.

AST-2 Alienware M15x 6Gb RAM and Intel Core i7 Q 840 1.87Ghz

AST-3 Alienware M15x 8Gb RAM and Intel Core i7 Q 740 1.73Ghz

Passmark: AST-2 1467.5
Passmark: AST-3 1443.5
AST 2 had a 6-10% better performance in all categories except Large RAM was -31%
www.PassMark.com was used to benchmark the performance of both computers.

Now for the Civil 3D test results.
