Oh wow, yeah. that's too step. The gap here had narrowed during a recent sale to like 60-70$ and you probably could've used it longer than 3 years.
If you don't have a DR4 already, you might want to consider the thermalright peerless assassin, which is like half the price of the DR4 -- and performs better/around the same. If you've got some spare 120mm fans lying around, you can get it at the same noise level too.
