This PC has an AMD Atlon XP 2600 (462) and it has been working since 2001. NEVER had an issue with it, most dependable bit of hardweare I've owned. I'v had nothing but trouble with Intel CPU's. Intel Outside please!
Not only this, today Athlons offers great performance to value ratios with most of their CPU's. My big box has a 3800 and thats still working (which I would expect as it's only a year old now).
