Sorry for the late reply, just back from vacation. A high-end workstation may be a good choice for medium-scale experiments (1000 to 10,000 fields of view). CellProfiler’s multiprocessing analysis mode could utilize all of the parallel threads, assuming that you had an appropriate amount of memory (256 - 512 mb / thread is my first guess) as well. If you have IT support and a cluster, splitting your analysis up between machines is more scalable (more fields of view requiring more machines on the cluster) and you would be sharing the compute among your organization’s users instead of having a computer that’s idle except when you’re running an analysis.
But, if you’re looking for a machine to dedicate to CellProfiler, that chip is well-suited for the purpose and CellProfiler can use much of the power right out of the box.
