Hey, I'm ready to purchase a new cpu, and I've narrowed it down to the Phenom II x4 965. However, on newegg, there's a 140 watt, and a 125 watt... and I don't know which one to get... I'm ordering the 125w tomorrow unless no one tells me otherwise.
140W was a C2 chip, the 125W version is C3. Lower power draw due to lower voltage requirements, slightly better overclocking, and slight improvements to the memory controller. Overall C3 is better, but not by any kind of significant margin.
