Just completed my new build with a 965 BE C3 at the heart and what a phenomenal beast it is! Upgraded from an Athlon 4600 and the difference is insane. Handles everything I throw at it and tasks such as video conversion etc are just a breeze. The stock cooler that comes with the retail kit is a tad loud at full tilt but not a major issue. This cpu would benefit form some Arctic Silver (5) paste and a non-stock cooler. Overclocking it is also a doddle and you can get 3.9ghz easy cooling the thing on air!
Update: I have now fitted a themrolab BARAM heatsink and the temps and noise have just dissappeared! Dropped mine to an idle temp of 28c and a full load temp of 45c. In fact the cooler Is soo good I know it could also cool passively! It is quite tall though so best to make sure it can fit your case! Worth changing the stock cooler I found in the end but don't get me wrong, the stock cooler does an ok job.
This chip continues to rip through most tasks, and for gaming is spot on! Plays everything exceptionally well. Very happy with this chip and it should see me for a while now, especially as the black edition has the unlocked multiplyer for easier overclocking if that your thing.
Update: I've been tinkering with an oc and it sits nice at 3.6 on stock by just updating the multi. beyond that a small vcore bump to 1.425 was needed to get 3.8 stable. I've not gone beyond that yet as I think it disables the cnq feature.
