We learned that Nehalem 3.2GHz should reach over 4GHz easily, and if you are a really good overclocker, you should hit up to 4.5GHz on air. Of course, for such a task you need a great motherboard.

Furthermore, if you want to go over 5GHz and even 5.2 to 5.3GHz you need to play with LN2 but apparently this is possible and it has been done with demo CPUs. These are some of the numbers you should be reaching once the CPU is out. 

Naturally, the Core i7 Extreme edition at 3.2GHz and overvoltage protection removed should be able to reach the highest clocks. It is safe to say that whatever speeds you’we seen on Core 2 Quad 45nm Yorkfield parts, you should be getting with Nehalems or you should at least be within that range.

Looks like overclockers will like this one; but beware, the memory speeds will suck, especially compared with X48 memory scores.
