I won't go that far, as there are others that perform as well or better. But it's a good choice and also helps cool the motherboard components down too. And it offers clearance benefits if you have a giant door fan on your case too because of the layout. I could actually move the door fan to it's normal position on my Dragon Rider test case that I review heatsinks in with the Genesis.
BTW, I am presently testing this heatsink right now as I type this, so I do know what I'm talking about.
For some other good choices, you might look at the Thermalright MUX120 if you are in the market for a mid priced cooler that gives good ram clearance. For higher priced (and even better performing) options, you also might want to look at the Thermalright Archon, Silver Arrow, Venomous X or TRUE rev. C. For Noctua, the NH-D14 is a very good choice. With Prolimatech, there is also the Megahalems Rev. B, but it doesn't perform as well as the Genesis or the Thermalright of Noctua offerings above. A couple of price/performance offerings to look at would be the Cooler Master Hyper 212 Plus and the Hyper 212 Evo.
With your budget, you also might want to look at a self-contained water cooling system such as the Corsair H80 too. It's as trouble free as high end air, since it's a sealed system and it works very well. I recently reviewed the H80 and was very impressed with the performance.
