I use a Hyper 212+.... And it has done good for me on a Q9550 @ 4.2 Ghz / a i5 750 @ 4.25Ghz / and a i7 860 (Just got it so haven't gone as far yet) @ 3.6 Ghz.
The point is that it is cheap.... but it's performance is one of the best out there. It trades blows with coolers that are $40 to $70 dollars more expensive then it.
Plus I believe it is compatible with any modern socket out there.
So the fact that you aren't clocking that high .... but it gives you room if you want too. Plus the low price of it. I would say go for it.
The only down side is that it is not as flashy as some of the other coolers out there. But that can be changed some what. You can easily add some high flow LED fans if that is what your into.
But even so.... I still think it looks really intimidating and bad ass.
