Looking at the scores, the 3.1GHz Phenom II X2 550 is pretty much equal to the 3GHz E8400. Our subject won 3 real-world gaming tests out of 5, but for the other benchmarks it lost seven out of the remaining twelve. So really, if it is inferior to the E8400, I would say it is by a tiny bit. The difference though is that the Phenom II X2 costs $102 whereas the 3GHz Core 2 Duo costs $165.
