Intel discontinues Pentium, Core 2 Duo and Core 2 Quad CPUs
Feb 08, 2011: Last October, we published a story detailing upcoming discontinuation of many Core 2 Duo and Core 2 Quad microprocessors, and two Pentium Dual-core models. Yesterday Intel published Product Discontinuation Notifications (PDN), that provide End-of-Life milestone dates for these CPUs.

overclocking on these varies greatly from chip to chip in my experience, my own did not really get to far past 3.5ghz.

the one i put in my wife's system was for more eager to please, 3.9 without a sweat on air.
