[FFmpeg-user] Dual Xeon VS Haswell-E, maximize fps

[Ryan M]

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.
