I think that depends on what you are trying to go for. If you're looking for extreme overclocking (voltage adjustments, etc.), look elsewhere. But if you are looking to get as much as you can at default voltage, any 865 or 875 based SFF will do. My SB61G2 (865 based) has a 2.4 @ ~3GHz, and my 9800NP at Pro speed. Nary a problem with it, either.
And I've seen some at sfftech go further.
