The small desktop machine was assembled in 2014 using budget retail components:
While the disks had already been upgraded the system lagged in speed compared to the bigger machine. I upgraded to the following components:
Vendor’s choices of the above come with substantial discounts. The Ryzen 5 3400g budget processor is on par with the 2015 top desktop processor i7 6700K: https://www.cpubenchmark.net/compare/Intel-i7-6700K-vs-AMD-Ryzen-5-3400G/2565vs3498
Switching the display from 1920x1200 to 3840x2160 forced switching from 60 Hz to 30 Hz. An upgrade resulted in:

“Hot on the heels of the release of the Radeon RX 580 and RX 570 launched earlier this week, AMD have released a new Polaris 12 GPU, the Radeon RX 550. It is a sub-$100 entry level GPU, targeted at those who want an inexpensive, low profile, low power and low performance component for mini desktop PCs or a minor upgrade on integrated GPUs.”
https://gpu.userbenchmark.com/Compare/Intel-HD-530-Desktop-Skylake-vs-AMD-RX-550/m33102vs3925
Steps performed:
removed side panel and slot cover
plugged in the graphics card
put back the side panel
moved the HDMI cable from the main board to the graphics card
Upgrade from the 6700K’s GPU to the Radeon RX550 worked without any tinkering; a pleasant experience!
Karl, it may pay to include the procedure needed to replace the system’s drive(s) with newer devices – more disk space – fewer ECC reports in the SMART output …
Whenever a component fails you replace it and you are done. However when a SSD or a HDD fails you got a problem. Uncle Carey tells you all: There Is No Such Thing As Back-Up Overkill! How I Protect My Client’s Data.
When it comes to upgrading your drives ATX main boards with their two M.2 and six SATA 6Gb/s connectors give you maximum flexibility at minimal costs.
Replacing HDDs by SSDs is highly rewarding and the most efficient upgrade for nearly every system. SATA SSD technology has matured and virtually every brand and model will give excellent performance at a moderate price. I prefer copying with rsync to cloning partitions.
The main board worked well with all distributions installed. However openSUSE Leap and Tumbleweed failed to suspend to RAM. Thus I sold it and bought a new one:

Ryzen with Vega graphics supports HDMI 2.0 -> 4K @ 60 Hz (@ 120 Hz with 4:2:0 subsampling).
https://www.gigabyte.com/de/Motherboard/B450-AORUS-ELITE-rev-1x/sp#sp
Support for HDMI 2.0 version and HDCP 2.2.(Note)
https://www.asus.com/uk/Motherboards-Components/Motherboards/PRIME/PRIME-B450-PLUS/techspec/
Supports HDMI 2.0b with maximum resolution of 4096 x 2160 @ 60 Hz
You need cable with support for HDMI 2.0+.
The new 970 EVO has fourfold capacity at half the price of the 950 PRO. With only one m.2 slot being available I proceeded as follows:
save old drive to iso file using Tumbleweed USB Stick.
remove 950 PRO and install 970 EVO.
install Tumbleweed on 970 EVO using default partitioning
boot into USB stick, mount old partitions using “losetup --partscan” and "mount -o subvolid=5 /dev/loop0 … .
use rsync for copying subvolumes
adjust /etc/fstab for new UUIDs and subvolumes.
reinstall grub
Installing Tumbleweed first and rsyncing has some advantages.
thorough testing of the drive using a pristine system with default partitioning
fast update through rsync; less than one minute real time
