cbrunnem :
how many benchamrk did it take to find that one. the one that is completely wrong and doesnt even have a constant ambient temperature. also any benchmark that shows the 212 evo better then the noctua nh-d14 is completely and utterly WRONG. that is not the case. the 212 is 10*c hotter in my experience.
they could have had a bad mount on the d14, seeing as the c14 was cooler, who knows what the discrepency was. Point is $100 doesn't 100% guarantee you a better experience.

a whopping 6C for $70 ... is it worth it?
This isn't even the same as overclocking Ivy Bridge.
even with water loops, ivy can't reach much past 4.6 ghz, spending $70-$170+ more won't get you very far. http://www.tomshardware.com/reviews/build-a-pc-overclock-benchmark,3276-5.html
other than that the stock cooler sucks, always at the bottom of all cooler reviews.
