For Q6600, normal 24/7 stable OC is 3.6-3.8 (the latter is unlikely though), and for QX9650 we can assume 4 -4.2GHz. So, 10-15% improvement in clock speed. Good, but not fantastic.

Besides, keep in mind that more affordable Q9550 and Q9450 will clock lower, especially Q9450 which is gonna be limited by low multiplier for sure.
