All CPUs still in production are at least SSE3 capable, unless someone 
can come up with one of which I'm not aware.  Intel compilers made the 
switch last year to requiring SSE2 capability for the host, as well as 
in the default target options, even for 32-bit.  All x86_64 or X64 CPUs 
for which any compiler was produced had SSE2 capability, so it is 
required for those 64-bit targets.
