If i have an AMD 64 cpu, can i install windows 64 bit now or are there any compatibility issues with other apps? antivirus, firewalls.... Thanks
Read this link http://www.microsoft.com/windowsxp/using/64bit/russel_exploringx64.mspx I think there are still quite allot programs/drivers which will not work under 64bit windows, mainly because there aren't any 64bit drivers or there are compatibility issues.
