News


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.

great value/ performance on this chip. outperforms the chips intel is selling at the same price (800FSB core 2's)
by plenty.

lacks ddr3-1333 & 1600 support however.
