Pros: After some soldering & rewiring these things, I managed to get them into one of my Dell PowerEdge 1900. The beast of a server went from being deafingly loud to a subtle & acceptable whirr.

Cons: None! They're great!

Comments: I got this processor the other day and compaired to the Athlon 64 3500+ my friend has, it sucks. If you plan on buying this processor, get a new heatsink and fan because the stock cooling is running at 60C idle for me, and also for a few other people I know. AMD for me for this generation of processors.
