Zett - my opinion only, after playing with a new BH7 for a couple of days, if you have a P4PE do not replace it with the BH7. I bought the BH7 to see if I could get more outta a couple of 2.0A C1's than I could with the P4PE. Both chips ran exactly the same on the BH7 as they did on the P4PE. I noticed that voltage fluctuation under load is much less on the BH7 than it is on the P4PE, but I expected that. Other than that, still can't reliably run one chip over 3300 and the other over 3200 on either board, so in my opinion either is a good choice. If you have one, don't swap it for the other.
