i was messing around in the bios settings in my p8z68-v LX when i came across the "ASUS Optimized" overclock settings. i enabled it and rebooted my pc and when looking at cpu-z at idle the core speed is 1.6GHz with voltage of 1v. but im game (BF3 for example) it bumps up to 4.4GHz and around 1.3v. what i want to know is this setting any worth it? and will my cpu last about 5 years? (because im planning to keep it for around that time)
