Summary: So do I think that the Athlon 64 3200+ (Socket 939 Venice core) is a good buy? Well, it depends on what is in your rig at the moment. For instance, if you already have a Socket 939 system and an Athlon 64 2800+, or Athlon 64 3000+ I would say no; barring some extreme overclocking the speed increase is likely to be minimal. On the other hand, if you are still running a Socket 754--or worse yet--Socket 462 system, and are looking to upgrade, the time is perfect to do so.
Pros: Good performance, Runs cool, Overclocks well, Low price
Cons: Stock S939 A64 3200+ not any faster than S754 A64 3200+
