I use:
  • a Mac Mini 2018 i3 3.6 GHz 4 Core, 32 GB RAM, 256 GB storage;
  • three displays, namely three x ViewSonic VS18705, type VP2756-4K 27 inch displays (one in landscape orientation and two in portrait orientation) (two connected using USB Type C and one using HDMI); and
  • MacOS Sequoia 15.5.

My previous computer was an iMac 27-inch, Mid-2011. I had only the iMac’s built-in screen; but, three years ago, I urgently wanted much more screen-space; and predicted (correctly) that before long, I would want three displays. As I recall, at the time: Apple did not sell a new Mac Mini that supported three displays at a reasonable price; or the lead-time between ordering and delivery was much longer than I wanted to wait; or both. So, instead, I bought a second-hand model - in other words, my 2018 Mac Mini. I was pleased with my purchase, as it was an affordable way of allowing me to experiment with first two, then three displays.

I use my Mac Mini for my work. An important part of my work involves my using Microsoft Excel. Over the past few months, various issues have arise. Here are three that come to mind:
  • some of the Excel spreadsheets I use are large and, when I press keys on my keyboard, there is a noticeable (and irritating) delay before the corresponding character appears on-screen;
  • I see quite a few “beach balls”; and
  • when the Mac Mini has been asleep and I wake it up, it sometimes, randomly, forgets the arrangement of the displays and their respective orientations, until I re-start it.

So, I plan to order a brand new Mac Mini and, provisionally, with future-proofing in mind, to opt for
  • M4,
  • RAM 32 GB and
  • storage 512 GB
  • for £1,199.

I am hesitating because this post says
If you have 2 4k displays let alone 3, never buy base m4 with 10 gpu cores. It is noticeably slow due to low gpu core count.

So, will an M4 with 10-Core GPU be slow and should I instead order a M4 Pro with 16-Core GPU?
 
Ignore the 10-core GPU warning.

A 10-core M4 GPU is almost a 1000% faster than the anemic UHD 630 in a 2018 mini. If you use an eGPU expect 10-core performance to be a bit faster than an RX 5500XT. A 10-core M4 isn't enough to go crazy and play X-Plane on 3x 4K monitors, but excel/numbers spreadsheets will get rendered no problem.

Side note: None of 2018 problems you described sound like a GPU issue. Excel/Numbers are more CPU intensive applications, but the jump quad-core i3 to a a 10-core CPU M4 should provide a huge improvement.

Thank you for your reassurance.
