Quad Q9650 overclocked to 4.0 GHz....

Thanks Leto

Actualy 3.8 GHz is quite amazing too,it's not that far behind the 4 GHz....the difference in performance is rather minimal....
OTOH,I didn't manage to go 4.2 GHz,so everyone has his own disappointment I guess....

For Rybka, it seems the Core i7 bonus (with HT off) is more like 30% than the 14% you quote

I did not understand you exactly what do you mean

,but anyway here is my explantation,why i think that the elo difference between i7 920 @ 4.2GHz and Q9650 @4.8GHz should be approx. equalant:

OK Sedat, I understand.
You are taking that from your Rybka Benchmarks.

The 30% figure I quoted were from position tests in the Rybka Forum (with only 1 core, in order to be reproducible)
