Re: New iMac 5K: M380 vs. M390 graphics

Get the one that's going to be easier to expand & upgrade as it gets older.

Photo editing (lightroom) is probably the heaviest lifting the machine
will do.  I know that Lr can use the GPU but I haven't been able to
find much information about the difference between the M380 and M390.

Now that the SSD component of the fusion drive is only 24 GB I'm not
sure how much of an advantage that is over the straight HD.  If I get
the straight HD I will almost certainly use an external Thunderbolt
SSD for most things, and use the internal drive for photo + music
libraries.  If I get the fusion drive, maybe that will be fast enough
on its own, I'm not sure.  If it's not and I still end up with the
external SSD boot drive, I'm wondering if the fusion drive will
actually be worse for photo and music libraries since it is presumably
a 5400 RPM drive.

(I guess, for the price of the middle M390 + 1 TB fusion drive model +
external Thunderbolt SSD, I could get the top standard configuration
with M395 + 2 TB fusion drive + slightly faster processor.  The 2 TB
fusion drive has 128 GB of flash.  I'm just not sure how that would
perform compared to an SSD boot drive).

Thanks for any advice.

Yeah, you can on the 27", just not on the 21.5" models.

One advantage of the newer iMacs is that they can be used as displays 
when

they obsolete out.


This is no longer true, unfortunately.

"Note: iMac (Retina 5K, 27-inch, Late 2014) and later iMac models
can't be used as Target Display Mode displays."
https://support.apple.com/en-us/HT204592



Probably for the same reasons Apple can't make a 5k retina monitor for use 
with MacBook Pros... Thunderbolt 2 doesn't have enough bandwidth to do it.


You'll need Thunderbolt 3 on both computer and monitor for it.

Double check that you can upgrade the RAM.  Probably still doable on 
iMacs, not still doable on macbooks.

Also check on how doable it is to replace the hard drives.

One advantage of the newer iMacs is that they can be used as displays

it turns out that my mini won't work with two high definition displays,
