Have just read an longer article about the fx8150 performance.

If you compare the pages(Seiten) 7 and 12 you can see, that overclocked, it is a good CPU.
They overclocked it from 3.6GHz to 4.6GHz without watercooling and big voltage tweaking.
Does'nt look so bad at me, since i plan to go watercooled anyway. (hate the noise of fans)
It might not be a big step above the PhenomII 1100T or the SandyBridge. But for those who have older systems it becomes interresting or wait a half year for the SB-E or Ivy-Bridge. (Even Intel has some problems by changing to 22nm)
