OCIA.net has posted their review of the AMD Phenom II 965 X4 Black Edition C3 Processor

Although AMD has had some exciting new mid- and entry-level chips come to market in the last several months, their top of the line Phenom II series has not seen much action since the beginning of the year. But since we won't see AMD's new six-core desktop Thuban processor emerge until next year, what we have to feed off of in the meantime is a new Phenom II core revision, the C3. Beginning with the highest-clocked chip, the 965 BE, the new core will begin to filter down through the rest of the lineup through next year. Enhancements to the core are expected to lower voltage requirements and thus reduce operating temperature, which can potentially lead to better, more stable overclocks. Is it worth the upgrade expense for a current Phenom II owner to make the change to the new revision though? Join me as I aim to find out!
