I did however come into the athlon64 by chance and decided to run with it. It's my desktop PC and runs CentOS 4.1 (fully updated of course) and my router/web/ftp/mail server runs i386 CentOS 4.1. Not noticing anything unstable, other than gftp; however, I was just curious about the implications of having x86_64 arch and what not. Thanks again. Alex White
