Windows XP 32 bit or 64 bit?

Should I use 32 bit or 64 bit Windows XP? Which one is faster for a MacBook Pro 2.6Ghz, 4Gb RAM, 200GB 7200 RPM hard disk?

I would use the standard Windows XP (32-bit). Win64 was made for the AMD64 CPUs and is I am not sure how much support it really gets driver wise, or how well it works with the C2D.

Thanks a lot.

I had XP x64 on a partition of my desktop before. It ran well, was quick, but didn't have much driver support. Some programs weren't compatible with it. Some programs look for SP2, which x64 didn't have at that time. I would recommend 32-bit because x64 wasn't noticably faster (I had 32-bit XP on another partition of the same computer), and is much more supported.
