KT266A is faster, and they are both equally as stable for the normal person... maybe a few minutes downtime difference in a freaking year... the KT266 is NOT unstable, and the AMD 760 is NOT alot more stable at all.. we're talking small small difference... i do know the 760 is quite a good rock solid platform, but the 266A is too.
If I were to buy one right now... KT266 hands down, no questions asked.
