Interesting AMD Athlon 64 Info: here, and to summarise: 2 Athlon64 CPUs will be launch on the 24th Sept: Athlon64, 2ghz (pr3200) 754pin single channel ddr, and Athlon FX-51, 2.2ghz (no pr rating) 940pin dual channel ddr (basically a rebadged Opteron). They say performance from looking at the Opteron can "blow the P4 out of the water in some tests", and that's just in 32bit code, so presumably 64bit code will run even faster...
