FrostyTech also has a chart for the AMD CPUs
You can see the Hyper 212 Plus is a little lower than some of the other coolers but still impressive. It's still about a 3 degree difference between the two models. It's still pretty high up on the charts and that price is really good.
If you're not going for that 4Ghz OC I think you're safe with the basic CM Hyper 212.
