Which is better to run at 200x12 on an Abit NF7-S ? The 45 watt is $77 and
the 35 watt is $87.

Hi

May be a guess but if you're interested in overclocking then the 35 watt
will be a better bet and only $10 more expensive i.e. if you do O/C then the
35 watt would produce less heat than the 45 watt CPU?

I wouldn't put it in those terms. A 35w CPU at (say) 2000MHz at (say)
1.75v will produce the same amount of heat as a 45w CPU at the same
settings. The two CPU's have the same core so there is no reason why one
should produce any more or less heat than the other.

However, theoretically the 35w CPU will be able to reach a given speed on
slightly less voltage and will therefore generate less heat.

Whether this is true in practice depends a lot on the stepping of the
individual CPU's: A good 45w stepping will easily outperform a poor 35w
stepping.

The 35Watt CPU, has a lot more headroom than the 45Watt CPU at the same
overclocked settings, to clock a lot higher.
