IIRC you have to use Linux to use the full 64bit now (most of the distributions have an AMD64 version). Microsoft delayed shipping of Win XP for 64bit to end 2004.
But even if you use Linux, make sure that your applications work with the full 64bit

Q: Which operating systems will support AMD64?
A: AMD designed its AMD64 technology to run all x86-based operating systems, including 32-bit versions of Microsoft® Windows®, Linux, and Solaris. Several Linux developers support AMD64 with native 64-bit operating systems, and Microsoft delivered beta releases of 64-bit versions of Windows for both servers and desktops in mid-2003. Microsoft has announced its plans to deliver AMD64 operating systems for desktop/mobile PCs and servers in the second half of 2004. AMD expects the AMD Opteron processor will support all major operating systems, including Red Hat, UnitedLinux, MandrakeSoft and Wasabi Systems (NetBSD).
i did a bit of testing with them about 6 months ago.
specifically looking at the computing power for server clusters rather than as desktops.
i think it was dual cpu's the 244 model (1.8ghz?) vs PIV 2.8ghz xeon. the amd won about 80% of the tests and if i remember correctly none of them had more than about 20% in it either way.
this was all server linux apps running in house c++ or java stuff, plenty of large data sets ~1gb and lots of message parsing processing.
i think the outcome was that we'd wait until the vendors (IBM, HPQ etc) came out with blade models and win64 was available, which is probably within the next 3-6 months.
so they were good, at least as good as the intel competition but the vendor ecosystem wasn't quite there yet, but that seems to be changing now. i'd be interested to repeat the tests with the new 248 cpu vs the 3.2ghz xeon. maybe the amd would win 90% of tests then.
i think the killer for my work will be a stable amd64 jvm, then sparc can finally be killed off.
