[citation][nom]ramon zarat[/nom]LOL.... some people are weird! Practical application? As if the purpose of this world record attempt had anything to do with "practical"! What's the "practicality" of a dragster doing 240Mph on a quarter mile? How about climbing Mont Everest? We do those things simply because we want to know if we can and because it's fun. It's called the human nature. Most of which is... unpractical![/citation]
Well, you chose bad examples. Dragsters are specifically machined an developed for doing what they do. People climbing the Everest train everyday and test the limits of the human body.
With extreme overclocking people are just buying cards that anyone can buy and drop some nice cooling and high current on them.
While dragsters and people climbing the Everest improve technology and knowledge about the limits of materials, mechanics and human body, extreme overclocking does not test nothing because they aren't using nothing specifically built for that. No test of special silicon made for high voltages, current and low temperatures. Manufacturers don't aim at extreme overclocking when they design their chips, people are just buying normal chips that at most are cherry picked.
With dragsters you are using tech specifically built for that, and eventually that tech somehow will benefit normal cars. With people climbing the Everest maybe better equipment for living on extreme conditions will be developed, or you get better knowledge of our environment.
With extreme overclocking there are no additional benefits than throwing hardware to the trash just for fun.
