Performance is equivalent, except in a few corner cases. Keep in mind that there are some cases where amd64 is actually slower, so it's really a wash, unless you know you're specific application will benefit from 64 bit. > Also what are the common problems, i.e. drivers, > applications that are known not to work under the > AMD64.

Last time I tried to run amd64 on a desktop, I had lots of trouble with misc problems here and there. Same machine running i386 is rock stable with no problems. My gut tells me that a lot of desktop apps and libraries aren't really mature from a 64-bit standpoint yet. -- Bill Moran http://www.potentialtech.com
