I think I agree with all you say except giving memory to a RAM disk. It would be much more efficient to just give all the RAM to Photoshop. There is an old saying that nothing improves virtual memory performance like more real memory. :-)

PS commands/filters may have GPU support but most of them still using CPU

Your current processor's benchmark is 3994 (PassMark) and my CPU is 8843
(Intel E3-1230 V2), it takes 12 seconds to startup on a 2.5" slow HDD. If
you invest on a SSD and a faster CPU like the i7 6700K (benchmark
11003), it
should be much faster.

If you have lots of RAM, I highly recommend the "ram disk" for PS scratch
disk. It is extremely fast even your image is a few hundred MB.

Thanks, Bob & ChrisB.  I will heed your advice.  I really need advice on
the importance and performance of of the GPU in using Photoshop... the
only thing that stresses my current machine.

I agree with Bob about OWC; they are an innovative lot.

On the other hand, Chuck is the sort of person that Apple is trying to
tempt to the Other Side, so a call to their sales team should be
fruitful.

I managed to buy a nearly new MacBook a couple of weeks ago – for a very
good price.  But the previous owner had probably left the thing plugged
to the charger and the battery condition was only 90%.  I talked this
through with Apple support (based in Athens :-)) and the experience was
very useful.  I then had an appointment with a Genius in Cambridge who
checked the battery for me.  It was fine, but he advised me how to keep
the health from deteriorating further: use it, don’t leave it plugged
in.

I was impressed with the overall level of service, and I bet the sales
team is up to the mark.

Now that I've had to go help a few unfortunate owners of new Win10
machines or (worse) upgraders from Win7 I have vowed I'm never going to
Win10. I am seriously thinking of turning myself into an Apple fanboy.

That, of course, requires running Photoshop on some sort of Mac
configuration.  I don't want a Mac laptop (yet) and don't need a big
monitor (already have one) so I've been thinking of Mac minis.  These
can be configured from about $500-2,000.  What do I need in the way of
CPU, graphics processor and memory to get good Photoshop
performance?  I
make extensive use of ACR to process 16MP E-M1/M5 images and need to
consider that the E-M1 MkII will likely have the 40MP mode or maybe
even
larger.  Of course, such large image sizes will not be the norm but
probably do dictate 16GB RAM.

My current machine is an HP desktop with 8GB and an AMD A8 5500
quad-core at 3.2GHz with integrated graphics.  Performance is
similar to
an Intel i3 3220 although the AMD's graphics performance is better.
This
has what I consider acceptable performance for 16MP images but hardly
bowls me over.  For some reason recent startup performance in Photoshop
has become much slower.  I've never timed it but it seems that it's not
really ready to rock and roll until it's been up for 20-30 seconds.
After that performance is normal.

I'd love to have something that's twice as fast or even 3 times as fast
if that's possible.

Thanks,
Chuck Norcutt
