Could it be possible that AMD is still fine-tuning its lastest k10 model? So that the performance can be further improved. Or AMD has to release the not-so-mature CPU to meet the deadline but AMD could not make mass production as there are still some bugs.
If so AMD is not willing to let people do tests freely..... And if lucky engough, when fully tuned, k10 can also be a good CPU for its generation......
Well, just some guess, I am also a bit disappointed.....
