Tongqing,
the CPU (AMD versus Intel) does not play any role for crystallographic
computing, but you'll have to decide whether you want to install the
64bit or the 32bit version of RHEL4.
32bit programs run a bit faster on a 64bit operating system, and with a
64bit OS you can run programs which require arrays of more than 3.5 GB
(seldomly needed in xtallography), but you will have to install in
parallel many 32- and 64bit libraries. This is no problem by itself, but
quite confusing at first ...
So I recommend the 32bit version.
HTH,

Dear Friends,
We are trying to get a server with dual AMD Opteron 2200SE CPUs running
Redhat ES4 OS. Does anybody have experience on compiling
crystallographic programs such as ccp4, cns….on AMD powered machines?
Will it be a problem? Or we should stay with Intel Xeon servers?
Thanks,
Tongqing
