AMD Duron
This is the chip that has wrested the "best overclocker of our times" crown from the fabled Celeron 300 (@450, natch). It's basically a cut-down Thunderbird (ie the new "Performance Enhanced Athlon", or whatever stupid name AMD are calling it this week), with the 256kb of level 2 cache cut down to a measly 64kb. However, this doesn't have quite as large an effect on performance as you might think.
On top of that, the overclocking is just plain rude. Almost every Duron is capable of doing 900-950Mhz; not bad for a circa £80 chip. There are issues related to clock locking, however; AMD decided to lock the multipliers on some of the chips, so overclocking it involves either unlocking a processor or getting an unlocked one. I cheated and got a guaranteed chip from OCuk, which was expensive, but saved me some hassle.
Anyway, the upshot is a have a chip with performance roughly equivalent to a classic (slotted) Athlon 850 or 900, which can't be bad. In fact, I now play all my games at 1280x1024 as a minimum. Which is nice.
My Celeron
I didn't buy this chip to overclock it. It was a 433MHz when I bought it,
and I knew I had a really good chance of getting 488MHz by going to a 75MHz
bus. As I was putting together a low-cost machine anyway, I figured that was
good enough.
I read a few reviews on the web, and they all said the same - that the 433s
will do 488 but no higher. There was one guy who got 541, but only by using
water cooling, and even then he had to keep use a few pounds of ice every hour
to keep the water cold enough for the machine to be stable.
So, imagine my surprise when my chip did 541, straight out of the box,
without even needing any voltage tweaking. It's not even in a fancy case; it's
an Enlight jobby with a front fan and pretty good airflow, but then the room's
generally pretty warm. My hardware monitoring reports the chip as running at
45degC, well within Intel's spec of 70degC.
Tragically, at this speed the PCI bus is running at 41MHz and it proved to
be too much for the harddrive, which promptly started giving read errors. So,
it's back at 488 now. Grrrrr.

This thing is really, really enormous. Unbelievably so. I should really get
a digital camera and put a picture of it up.
