It all depends upon which software *you* run. I had a dual core
E6400 previously, and now have a Q6600. The E6400 was
overclocked to 3.2 GHz at stock voltage and was 100% stable.
The Q6600 is overclocked to 3 GHz with a voltage increase of 0.1 volts
and is 100% stable. I would demand no less. Both required aftermarket
cooling. For the types of applications and games I run, I appreciate the
occasional 50% better performance of the Q6600.
Intel designs its cooling solutions for a percentage of maximum CPU
usage. That means that for extended full power usage, the stock
cooling system may be inadequate for some processors.

Stock cooling is about at its limit with the 3 GHz E6850 for extended full
power usage. For the higher speed 65 nM quad core CPUs, I am certain
the limit would be exceeded, resulting in CPU throttling to control heat. I
find fault with stock cooling for both the push-pin mounting system and
the noisy high speed fan. I've put enough systems together and stress
tested them to have this opinion. I like to replace the push-pin mounting
system with these, which is secure and doesn't have a tendency to flex
the motherboard:

100% stable is just that. Significant risk of errors is putting together
a stock system and running it at stock speed and not knowing where
exactly that limit of stability is. You could be sitting right on the edge
and not even know it. Your memory could be at it's limit. Your
motherboard could be undervolting or your voltage could fluctuate wildly
as power demands change. As for the Q6600 at 3 GHz, yes, aftermarket
cooling is required for extended full power usage. Mine just happens
to also be quieter than the stock cooler.

This really has nothing about being grown-up. It's a choice we have
each made based upon different perceptions of the same reality.
While I have made a significant investment of time to insure stability, I
would do the with a stock system.

I think you are putting too much significance on three gigahertz, perhaps
comparing clock speed to what you have now. My wife's XP system has an
E4500 at stock 2.2 GHz speed with 2 GB DDR2 and integrated graphics.
In "normal use," which I define as not 3D gaming and not video editing, I
can't tell the difference in speed. Even her most demanding Flash based
Webkinz games play smoothly.
