Altering clock speed on GPU

I've never had a problem to date (touches all wood in sight) with any form of overclocking. It's all about research and stability. Find out what a suitable overclock for your setup, this goes for CPU, RAM and GPU settings and adjust carefully and slowly over a period of weeks.
I have a stable OC profile for my Q6600 that is at 3.4GHz which for a 2.4 stock Quad isn't bad. I've got it to boot at 4GHz but not for long. But I didn't just jump straight to 3.4, I started on 2.7GHz and moved my way up making sure it was stable all the way.
But better to be safe than sorry, as hotstuff said don't do it

Conversely, I don't overclock anything thesedays. The extra stress on the components can result in shorter component life and I find I'm just not struggling that much for those extra MHz...

This.
I have a Q9550 at stock speed (2.83 GHz) and a Radeon 5870 at stock speeds - I doubt I'd really be able to tell the difference with any kind of overclock.

Your 5870 will be getting bottle necked to an extent by the 2.8GHz, but if you are getting FPS you are happy with then it is all gravy. I currently have no OC on my machine at all. I do it more as a technical exercise than anything else. It's also something I enjoy doing more than anything. My major reason for the OC originally was to test how much of an FPS improvement I'd get and also back when I first got this chip a few years ago was seeing how mental a 3dmark score I could manage with a relatively priced rig.

I tried a small overclock on my 5870 and it became very unstable very quickly - so I've had to leave it at stock speeds anyway

bob overclocked my Q6600 to 3.0GHz way back at i33, and it's been steady as a rock. The Q6600 is an inhuman monster of a processor.
No the original old card I underclocked,a "8800GTS 320MB"
The new card, a "9800GT 1GB low power" comes with software that allows you to overclock it - can hardly believe they encourage it! Needless to say I disabled the software, the driver on it's will do nicely thanks very much.
