There's no longer any pressure for GHz any more. Intel have dropped GHz-marketing and the P4 lineage like hot potatos, because they have pretty much got them into a deep cul de sac.
Even considering just single core, GHz aren't needed for performance, because you can have execution units in parallel, and feed them out of order, AMD style.
GHz will continue to rise. But more slowly, as new manufacturing processes becomes available.
Heat rises much faster with clockrate, than speed.
My guess is, we might see 5GHz by the end of 2006, early 2007. But it really doesn't matter what clock. Those CPUs are going to be so much more powerful than "5GHz" would indicate.
My thinking is that prefetch, cache handling and memory controller is the big challenge area for increased performance.

Since the first Tbird, I never liked P4s high prices compared to thier fantastically cheap AMD equivalent counterparts. Now we have a heat issue and thus a correspondingly noise issue which totally puts me in the AMD camp even at the same price as the A64's are. Not to mention Intels new socket practically designed to break and overclcoking block issues as yet unresolved.
