It is an AMD 64 X2 Dual Core 3800+
Was that the 64 I was looking for? I'm usually pretty computer savvy, but I've never actually upgraded operating systems before. I've always ended up needing a new computer by the time I was ready to upgrade anyway.
*EDIT*
I tried downloading the 64 bit version of Windows Easy Transfer and at the end it told me update.exe is not a valid WIN32 file and closed the extraction. What does that mean?
