I found this article regarding memory throughput and a discussion of
AMD-Opteron NUMA architecture. The conclusion is that only in 
specially customized applications one can take advatange of the
higher memory throughput.
Otherwise the memory bandwidth is limited to the FSB BW, 6.4 GB/s.

The article can be found here:

Just a last question, before I'm gonna place the order for the hardware:
with the above Intel XEON 5080 CPU I would be able to address e.g. 32GB
linearly and there is no hitch?
