I find that people who overclock don't really have anything important to do on their comps. Overclocking will usually lead to decreased stability and not forgetting it takes time to overclock/verify overclock some more, time I haven't got.
I have a 1400 tbird which is expensive here in the UK, I don't have the money to replace it if I screw it up, I have already lost an 800 to OC'ing, and yes I know what I'm doing.
Sometimes chips don't die straight away sometimes it gets worse or weakens the component badly, my 800 would BSOD randomly but would still run hours of demo loops, this is not acceptable when you have important work to be doing.
It's not in my nature to OC, I don't like jepordizing my equipment's life span, I wouldn't run my Home Theater equipment out of spec for any gains.
OC'ers seem to have little respect and/or understanding for sensitive computer components, they pluck the standard fans off them, splash AS epoxy all over them and then chuck 'em in the freezer/oven/dishwasher when they don't work!
People that overclock top of the line chips and Geforce 3's are just fscking crazy (I won't say stupid not wanting to start a flame war).
That's not what OCing is about anyway, sure if I had a comp that I didn't do work on and the bits were relatively cheap, 700 Durons, Celerons etc. then Hell Yeah I'd overclock.
With current chip prices it's hardly worth it is it? What with the extra cooling costs (and noise!) from a $$$ standpoint at current prices it's not really worth it.
I view OC'ing as a hobby for some, I'm not knocking it atall, OC'ing is fun, you learn alot too (some bad habbits though) but for me stability is No.1, I find it much more rewarding having the smoothest most stable comp than an extra bit of speed.
This is MHO
Peace.
