Performance of 64-bit vs. 32-bit Windows Dual Core

mikemuch writes "ExtremeTech's Loyd Case has done extensive testing on the same dual-core Athlon X2 4800+ system to explore performance differences between Windows XP Professional x64 and good ole Win32. The biggest hurdle is getting the right drivers. There are a few performance surprises, particularly in 3D games."

The spyware can all be run on one of the cores while the other can be used to get work done. I'm getting one for my father-in-law.

Microsoft recommends other operating systems

[serano]

A few months ago I bought a new AMD 64-bit processor and mother board. I installed XP Professional 64-bit edition, but the wireless MS mouse and keyboard I had wouldn't work. I couldn't find 64-bit drivers anywhere on MS's site, so I gave them a call. The person on the phone told me the keyboard and mouse wouldn't work with XP 64 and suggested I try another operating system. I asked if she recommmended Red Hat or Gentoo, but she just said, "No comment. Is there anything I can help you with?"
