I have the p4-3.0 prescott I pulled from my laptop in my desktop now and heat just pours out of my case. That is at 3.6 GHz and 1.3625v (which is very low).
I think it's only a gpu RAM heat issue if you get artifacts after a few minutes, other than that, they just can't handle the current speed.
i read somewhere, i believe anandtech or tomshardware a review/comparison between the northwood and the prescott, and the conclusion was that the prescott when overclocked was more stable than the northwood, i believe the comparison was with a 3.4 chip
