I agree with you here, but more like GPU overclocking. Pre- boosting you'd have a set speed, i.e 3.4ghz. put any old cooler on it in any old case with next to no cooling, you'd be running at 3.4 and getting 4.2 would be easy with a good cooler, I ran a 3770 at 4.2 for nearly 7 years on a £65 scythe cooler
Now keeping any kind of clocks is reliant on good cooling, I mean 230 watts is a mental amount of heat to deal with on a processor! 10 years ago being able to pump enough power into a cpu to generate that sort of heat was extreme overclocking, huge open loops or sub zero.
Overclockings not what it was. it was for the nerds that wanted to spend a little extra money and lots of time, its the other way round now. You can spend hours now and get maybe a few points. Then some kids mum buys him the top board, sticks on auto and is just behind your 4 hour investment.
