It depends how big your simulation systems will be. Cache size, number
of cache levels and bus speed can all also be factors in memory-latency
issues. Any other load on the machine will also be an issue. Thus it's
hard to give even a vague answer on the above information. The only real
test is to get the hardware and try it. If you're possibly buying lots
of boxes, a vendor might let you have a trial.
