Huh ?
If you look at the overall population using Intel x86-based CPUs, there are way less than 1 percent of them overclocked. Probably not even 0.1%. You guys are all biased, because you read websites like AnandTech. But in the real world nobody bothers.
Businesses, organizations, universities don't overclock their servers or desktops. Too risky. Too much hassle.
People don't overclock their laptops. That uses too much battery life, and makes laptops overheat. If you think performance is so important that you want to go through the trouble of overclocking your laptop, just buy a desktop.
Most people just do email, surf, twitter and facebook. Do some online shopping. And maybe do taxes once a year. No need to overclock. But also, they lack the skills or guts to even change one setting in the BIOS. ("WTF is a bioz ?").
Most gamers have no clue about what's inside their machine. Yes, suppose there are a million gamers who overclock their PCs. That is still not enough to be significant on a world-wide scale.
On a total of 1.5 billion PCs in use worldwide, plus 50 million servers (that are Intel x86 based), that one million gamers is less than 0.1%. Google alone has 1 million servers running (all x86-based, afaik). If you look at all the Intel-cpus that are not overclocked, you wonder why Intel bothers with K-versions of their chips.
