;About the only bad thing I've heard about the K6 is that it is not as

This is correct, the AMD chips are not as proficient in floating point
operations. This is not only documented but evident when playing such 3-d
based games as Quake--a similarly clocked AMD chip will not be able to
cope quite as well as an Intel, making them not very impressive game
engines. This could be a part of the price ratio, but who knows such
arcane facts.
