I don't know that it is realistic to have 8 systems running though. If I can pay more and have the approx same amount of throughput with one system, that would be better. I just don't want to pay like $4k more (for the Xeon vs Haswell-EP) and only get a few more fps out of it. If stepping up to Xeon allows ~40fps like Sean said then it is probably worth it. Thank you very much for the input.
