None of those benchmarks are enough to outclass a 3.2Ghz P4 Northwood... They look still look great, though.
Also, 64-bit support from the OS might give a small boost to 32-bit software running on A64. But only 20% of all software, at best, will have full 64-bit support at early 2004...
I hope they get their software support right! They're depending on it.
