It would be very hard to determine the Athlons stability when there are multiple platforms and system configurations that may react differently. If you're looking for general system stability, then there is one thing to know. AMD has made strides over the past three years to maintain superb system stability with their chipsets and CPUs. If you were to look back on the Super Socket 7 days of the K6 and K6-2, there were multiple problems with add in cards and video related issues with the poorly implemented AGP bus architecture. This is mainly a motherboard chipset related issue from VIA. Which is why we have seen AMD release their chipsets first when something new is introduced. Up until the AMD 760 chipset was released, I was using an Intel Pentium 3 system with the very stable Intel i815 chipset. The current AMD 760 is very mature and is rock solid in terms of stability. AMD has made sure this chipset was as compatible and stable as possible before release. The current AMD Athlon supporting chipsets have gone a long way with stability since the introduction of the AMD Athlon two years ago.
