In the past I've had some bad luck with AMD chips. The whole K6 series screwed me royaly. I'm looking to put together a system for myself. It is going to be my primary system, doing lots of graphic and video work... thus the AMD chips seem to be the primary choice. I'm not going to overclock the processor as reliability is VERY important to me. So here's my question. How stable are the new series of AMD Thunderbird processors..? I'll do the fan upgrade as I have heard they are VERY sensitive to cooling problems. Let me know you thoughts.. I'd also like to hear some mainboard match's.
