Of course the wait is for better compilers also now to get the athlon64 shown faster. >The athlon would run at about 2 Ghz in april 2003 if a P4 with some new compiler for the athlon64 is at say 2.53Ghz equal to a 1.2Ghz Athlon64 then that means: 2.53 / 1.2 = 2.1 factor difference. So the P4 is only equal to that when clocked at around 4.4Ghz However, the P4 can only clock to 3.5ghz at most according to laws from nature which says that higher clocked processors in 0.13 need more power when clocked higher. Right now it is already consuming 100+ watt at 3.06Ghz. So unless you use liquid cooling it won't ever get to 3.5ghz at 0.13 micron technology. In short that makes the athlon64 a killer cpu IMHO for the PC.
