HardOCP has just released the results of their Windows XP x64 Edition benchmarks. If you've been contemplating getting into the 64bit OS and hardware, I suggest you wait a little longer.

The focus of this article is to determine if upgrading to Windows XPProfessional x64 Edition with an AMD Athlon64 would give us a bettergaming experience in current games. We used eight games for ourevaluation including one that supported Win64 AMD64 specifically.

What we found isn’t too shocking really, but rather reassuring. In allthe 32-bit games tested, we saw overall static performance usingWindows XP Pro x64 Edition. The only game in our lineup that had aspecific Win64 AMD64 instruction path, The Chronicles of Riddick,actually performed worse in 64-bit than it did in 32-bit Windows.
