Why isn't sometimes on there?
As for OCing, well, not so much anymore. My 1366 i7, even at its stock speed, plows through everything I throw at it. I haven't had the need to overclock.
I initially got into overclocking in '05 with my first self built rig. However, the CPU I chose, an Opteron 165, had a locked multiplier and would bog down in some games due to it's relatively low factory clock speed.
So out of necessity, I overclocked it. I eventually ran it @ 2.6 24/7. Then I could play all of the games I wanted without issue. However, I made that $300 CPU run as fast as a $600 CPU. And I believe that was the whole point that the article is trying to make.
Has overclocking seen its heyday, quite possibly as it's becoming more mainstream. I think that the manufacturers have caught on to it, and there's no more "pulling one over" on "the man!"
I think it was the thrill of doing something that you're not supposed to. And now that everyone's doing it, it's becoming boring.
Kind of how the Netherlands made pot boring by decriminalizing it. Less Dutch people smoke pot now than before the decriminalization because there's no more excitement that you might get caught. etc.
