I can comment on some of this.  A hot GPU will help most in Pr if you =
stack GPU accelerated effects, and for the encoding / export of H.264.  =
Ae hasn=E2=80=99t gotten around to using the GPU on too many effects =
yet.

You didn=E2=80=99t say what codec your source footage was.  Long-GOP =
codecs will stress your CPUs more as the footage is more compressed.  If =
you layer several highly compressed Long-GOP clips, you can expect =
playback performance to suffer.

I=E2=80=99ve not noticed much difference in OSX versions as far as =
Premiere performance, up to El Capitan, 10.11.6.  Newer OSes seem to =
boot faster than the previous ones.  SSDs boot faster than spinning =
disks, too.

Your MacPro5.1 should hold 128 GB of RAM.  I recently upgraded to that =
model from a 3,1 with a max of 32GB RAM, and I was having to purge the =
RAM frequently, as the RAM would fill up and start dropping frames like =
crazy.  Now, with 128 GB of RAM on my 5,1, with Ae running =
simultaneously, I=E2=80=99ve so far not maxed out all the RAM, and have =
only gone as far as like 24GB left (which is what my settings reserve =
for other apps). =20

I have the hottest GPU for Mac, the Nvidia Titan, and the combo of the =
RAM and the GPU has made a substantial difference in terms of render =
times and real-time playback (vs. the old 3,1 lesser equipped with RAM =
and Nvidia K5000 GPU) of the sources I receive from clients, which is a =
variety of AVCHD, AVC-Intra, Sony MXF, Sony XD-Cam, ProRes, etc.  I =
often edit with 4K and UHD sources, and most often finish at 1080 HD.

It might not be wrong to infer that UHD HDR will use more RAM.=20

A lot of producers / shooters have been seduced by 4K, and buy cameras =
with a crappy Long-GOP codec that slows the native post process.  That =
said, I can generally play back 4K without dropping frames that isn=E2=80=99=
t in a RAW format.  I rarely have more than three or four video streams =
playing simultaneously in Pr.
