So, my conclussion after reading about 5 reviews and many threads is that the prescott sucks, badly.
I mean, yeah, it has more transistors, has a new set of instructions and a better HT, BUT it's too hot, consumes too much power (<-- not sure about this) and it's slower than it's northwood counterparts, these things are VERY important for me, especially because I'm talking about notebooks, and if the reviews are right, Prescott will suck it's batteries dry in a cinch, and if the 3.4 (or 3.2) northwood is faster than the 3.6 Prescott, you can't get lost anywhere. As always, comments appreciated.
