According to most public information, the AMD chips receive a modest performance boost when going to 64 bit in most situations. Core 2 chips suffer a small penalty when going 64 bit. I suspect this is due to the cache hit rate suffering which, with a traditional north bridge, would have proportionally more effect.
Vista is really pushing 64 bit, but that's partly due to the new driver policy. 64 bit Vista has more, harder to bypass, DRM as compared to 32 bit. Every driver has to be blessed by Microsoft. -- Geoffrey D.
