There doesn't seem to be too much special with this particular silicon. For the same price there are too many other processor choices that offer better performance in every other area - an Intel Core 2 Quad Q6600 is virtually the same price (and probably less following the recent price cuts) and offers oodles more performance, and many of our readers can testify to building a very quiet PCs based on this CPU.AMD's Phenom X4 9350e Review
We're struggling to think of situations where you'd absolutely need this CPU - the only one we can come up with is if you wanted a quad-core mini-ITX board that's limited to 65W. This would be the only option that would fit, so it wins by default. But then again we fail to understand why you'd buy this over a Phenom X4 9550
Essentially, unless it fills a specific application you require, then this CPU is not for you.
