Athlon II X2 benchmarks

May 03, 2010: A few weeks ago we acquired a lot of Athlon II processors with C3 core revision. Although we posted pictures and individual benchmarks to Athlon II CPU pages, and added the results to our benchmark database more than a week ago, we decided to provide benchmarks in more readable format, i.e. as a review.
