Okay, I think something is strange with my finding. It's on different board so that may be one of the reasons why I get different CPU score under 3DMark Advantage. Set both to the same default speed (Turbo 24x133) of 3.2Ghz, I get 34357 CPU Score for my MSI Eclipse Plus with the i7 950 and I get a CPU Score of 50484 for my EVGA Classified 3 with the Xeon W3550. Why are their score so different? Is the Xeon really that much of a better performer than the 950?
