Any speed for those three CPU families will wreck a 2.4ghz Pentium 4. Hell, a 2.4ghz Pentium-M will blow just about anything away, hehe.
The best buy from those families, in my opinion anyway, is the 1.73ghz Pentium M. It's roughly the equivalent of a 3200+ Athlon64 or Turion, though the Pentium-M's main strength is gaming (it's a bloody monster) which benefits the most from the actual CPU architecture as opposed to memory bandwidth and latency (one area where the P-M is lacking). Other stuff will run fine, but don't expect it to scream along like it will on a decent Athlon64. So I guess I take that back, get a Turion64
