I wouldn't call it on par tbh.
But it ain't that bad as some people make it look ( the FX-4100 vs Thuban x4 is a different story, it's scary, very scary ).

I have the numbers from the 2600K with the RAM @ DDR3-1866 9-9-9-24 for a direct and fair comparison, but I haven't gotten around to create the charts yet.

If the FX-8150 find its way to 170$ then I'd say that it would sell a lot.
As long as it remains pricier than the 2500K I won't recommend it, unless forced to :p

It barely copes with the 2500K except in a few apps, running a 100 apps test suite, it would win around 20 apps, tie the 2500K in 30 apps, and lose the rest lagging behind from just a bit, to a lot.
