Enhanced Virus Protection
The Athlon64 can run any operating system a normal athlon can.
I think the original poster's question is whether WinXP "gold" will install on an Athlon64 (err, oops, I guess that's what you said already

). Sure, after installing, he can and should update WinXP with Service Pack 2, either by going to Windows Update or by
pre-downloading the whole thing and saving it on a CD. That will get the Enhanced Virus Protection going, gotta like that
Burtie21, if you are not up-to-speed on keeping your fresh WinXP installation from getting worms, you might want to check my tips
here, with the basic idea being that you don't take a fresh WinXP installation and plug it into a broadband connection without a firewall (hardware or software), or even dial up to your ISP either. If you need a firewall software, the free version of
ZoneAlarm will get you started. You'll want to pick between ZoneAlarm or the WinXP SP2 firewall in the end.
