One reason for going 64-bit is larger address space for applications. If 
you are not doing high-resolution Finite-Element analysis or C.F.D. or 
astro-physics, the i386 would probably be OK. Of course, there is then 
the question of 'Why did you buy an Opteron/Athlon64, only to run a 
32-bit OS ?' :-) I am also on the SuSE AMD64 list & they are having 
their share of problems with their current release (9.3). I have been 
wanting to build a simple Opteron compute server for about a year now, 
but have been scared off by the apparent lingering stability issues in 
SuSE 9.2 & 9.3. That's one of the reasons I am here now, trying to see 
if things are better w/ CentOS :-).
