I've seen 4400+ CPU reach 2.9ghz on a Zalmann 9500, I guess the guy got a lucky CPU, I've also seen dud 165/170s that only got to 2.2-2.4ghz max, so don't say it's guaranteed. A 3800+ easilly gets to 2.5 or 2.6ghz on air cooling, my friend has one at 2.65ghz on air.
A 4400+ usually get 2.7GHz - 2.8GHz and usually a Opteron 170 gets 2.7-2.9 or 3GHz if you got a good CPU.
But I agree that that the Opteron 170 is a better choice. I just don't like it when people say that that Athlon cores don't compare to Opterons when they get around the same range. But since the Opterons are clocked lower, it makes them get higher OCs then the Athlons.
