My understanding was that no version of Windows would work on an 8-processor computer at this time. The "Windows XP Professional, 64-bit Edition," for example, is currently good only for dual computers [as of earlier this year]. I am not sure if this has changed recently, however. I cannot say about Windows 2000. Are you absolutely SURE it would work on an 8-processor computer? I know Microsoft advertises that they will support the Itanium line of Intel processors, so it would just be a matter of time before a 64-bit version of Windows would be available for 8-processor Itanium [Madison] computers.
