Maybe its a habit or addiction, or maybe some of us just can't get past the Hot Rod days of our lives, with Headers, Dual 4Barrel Carbureators, High Rise Intakes, More power OOOH YEAH. Maybe we need to start Overclockers Anonymous, as for myself my machine is overclocked right now, and I'm keeping it that way, because I've stumbled on the perfect settings for everything I'm running, its more stable and solid than the standard settings performed at. Theres + and - factors in every piece of computer hardware manufactured its just a matter of finding the proper threshold without using it as an alternate home heating source. And sure we're shortening the life of it but do you really think with technological changes happening as fast as they are, that our Top of the line machines will not be Dinosaurs in less than two years, so how long do you really expect your present setup to last. There is a difference between finding that perfect sweet spot and everything going up in smoke. Have a good day!
You never know what you can do until you try.
