the best i can get for my motherboard so it the same amount of watts is the 945, I don't want to risk using a different value of watts...
the 945 is 95W, while the 965 is 125W
Fairly certain that value is the TDP, the amount of heat it dissipates, it only really pertains to CPU coolers.
If I can put a Phenom II on a Dell stock motherboard then I have no doubt that you should be able to without it breaking
