My guesstimates would put the PII @ 3GHz to be a bit behind Q9550 @ 2.83GHz. Assuming hypothethical perfect frequency scaling, a PII @ 4.5GHz would be about as fast as QX9650 @ 4.2GHz. Of course, there's no such thing as perfect frequency scaling as memory, latencies, HT and NB speed limits are factors as well. And also depends on the applications you are using..
