I am runningCord2 Duo E 6700 2.66GHZAsus 8800GTX 328MB4GB 800mhz ramAsus P5n32-E-SLI motherboardand a 600W power supply.Althout i've had no problem handling any game at its max setting, i decided to push my computer to its limits recently.I overclocked to 3.2GHZ i believe if i recall correctly and my system was very unstable. I have 7 fans mounted on the case, yet the temperature increase, i felt was defnitely going to decrease my cpu's lifetime.Anyway i heard that processor run at like 200Mhz higher at the intel lab, and they downgrade it for safety. This is just what i;ve heard^_^Overclocking is great if you have proper cooling like a sick watercooling system in my opinion. Other than that its a pretty huge risk
