Maybe i am crazy, but i thought that e8600 work bigger clock speed than e8500. I overclocked e8500 with boxed air 4.5ghz and with water 4.9ghz, very sad if e8600 is that bad

I sell that and buy e8500 If i overclocked e8600 10x440fsb = 4.4ghz compared i overclocked same prosessor 9x 489fsb = 4.4ghz, can i get more power to ratio9 setting?
