I don't like to OC.
OC makes older the CPu's life with 700 % . So no OC for me.
This may be true, but the Celeron 400 that I overclocked to 500 was still chugging along about 5-6 years after I built and overclocked it. I only stopped using it because the system was outdated. My mobile Athlon XP 2600+ overclocked from 2.0 Ghz to 2.5 Ghz for years. It outlasted the mobo and a couple PSUs along the way too. My E6400 has been overclocked from 2.13 to 3.2 Ghz since September 2006 and is still running strong. I don't doubt that overclocking shortens the life of processors. More than likely, though, the processor will be outdated before the life would run out of it anyway. Both my Athlon and the Core2 were overclocked with increased voltages as well.
In addition to those mentioned I've overclocked another Celeron 400, an Athlon XP 1700+, a Mobile Athlon XP 2400+, a Barton Athlon XP 2500+, a Sempron 3000+ for shorter periods of time and have never lost a CPU as a result.
