Intel Quad Core Q6600ES G0 stepping >> Quad prime@3.9GHz > 4GHz+ benchable

So if we are seeing around 3.9Ghz ES. So would 3.2-3.4 retail box be a reasonable estimate?

omg ES is no SUPER hardware, they may be cherry picked... but the final silicon will do better! and worse! the main question is, will it do AS GOOD on AVERAGE? (we hope so..) but there will be "golden chips" for sure, which will clock even higher and those chips that don't clock as well..

the only possible way would be Intel changing the (final) silicon for better yields, but lower overclock (why do you need stable 4ghz chips if you can't release them because you are power constrained..)
