"It's no secret that Intel has been dominating the processor market the past few years, which is why we decided to go with an Intel based system for the Mainstream build. Although the Kentsfield core has been out for some time, prices have only recently fallen to the sub-$200 mark. In fact, the Q6600 made our Performance build the last time out, so it is still quite a capable processor for Mainstream computing. The Q6600 operates at 2.4 GHz, 1066MHz FSB with 2x4M of shared L2 cache. This processor has an excellent price point and is extremely overclocker friendly."
