The 965 BE is fairly easy to overclock given that you have some sort of aftermarket cooler. If you don't, you may not be able to overclock much past 3.6mhz. I was able to get mine to a stable 4.1mhz with a max temperature or 60c with a Coolermaster Hyper 212+. The phenom II BEs have an unlocked multiplier which means you can probably get an OC of 3.8 without even touching voltages. I'd direct your attention to this brilliant thread: http://www.tomshardware.com/forum/274820-29-black-editi... which I found useful for my first time OCing.
So, I'm curious if the Phenom II CPU will bottleneck he HD 7950. Anybody know whether it will or not?
You will be ok with that cpu. I would look to getting a new cpu in the near future though but if your only using 1920x1080 on a single monitor then you'll be ok mate. Amd has a setting for overclocking your cpu in ccc. Ive never used it though myself but id advise read up first before you try.
I have a 965BE at 4.0 with a coolermaster hyper 212+. Doesn't go past 53 degrees most of the time.
I can only get 4ghz out of my 975 be. I could get 4.3 with my old hyper 212 but changed it for a antec h20. Temps are not as good with the antec and I lost the brackets for my hyper 212. I may go back to air cooling. And maybe learning to maximise my o/c capabilities. I'm not to confident on pushing my cpu's. I'm chicken.
