Go with the P&C if you can use that much power. It is a very solid power supply and is a steal for that price since it is only a couple of percentages shy in only one category of getting a Gold rating in energy efficiency.
I did this same search less than 6 months ago, I read quite a few reviews and found that the P&C power supply stood with the best of them.
That being said I agree with rolli, if you aren't going to come close to using 950W then there is no reason to buy this. Efficiency gets worse quickly if you draw less 70% of the total wattage output of a PSU.
