i really doubt that this is just a speculation from the Intel Vs AMD wars. with that said i dont mean that the K8 cant have a bug. if this has been identified by the AMD engineers, they will eliminate it in the next revision of the processor. u should ask AMD about this.
I hope K8 is ok .. but in IC design . chip have bug is usually ..
like P4 or Xeon also have bug .. if K8's bug can be remove by
"BIOS" .. I think it will ok ..
