Benchmark Reviews posted a review on the AMD Athlon-II X2-255 AM3 Processor

In late January 2010, AMD released a new series of processors that fills in some of the gaps in their Athlon-II and Phenom-II Dual, Triple, and Quad-Core Lines. Most of the newly released processors are really just 100MHz clock speed bumps on the old versions. We have also seen the addition of some triple and quad core Athlon-II processors. In this article Benchmark Reviews focuses on the newly released AMD Athlon-II X2-255 AM3 ADX255OCGQBOX processor. Based on the Regor core, the Athlon-II X2-255 has a 3.1GHz clock speed, up 100Mhz from the Athlon-II X2-250 at 3.0GHz which was released last summer. The Athlon-II X2-255 is at the very low end of the newly released processors and represents a value based market at only $75. Benchmark Reviews is going to use the Athlon-II X2-255, with its support for DDR2 RAM up to 1066MHz as well as DDR3 RAM up to 1333MHz, to show some of the great upgrade options available for consumers who have been waiting for a low-cost option for a better computer system.
