overclocking does NOT reduce system life
HIGH temperature is what reduces system life. in our weather 50-55 is the max that temperatures should go..
every 10 degree increase above operating temperature reduces component life by half..
i am using asus board g33chipset.. and sapphire ati 4830.. i have had this system for long time now.. recently changed the casing only. i built this system over a period of 4 years upgrading twice..
