Thumbs up

Agreed that desktops have fewer power saving mechanisms than notebooks, but notebooks are so much more mobile friendly, that I only use notebooks for live usage.
(Almost) all the performance killers in notebooks can be eliminated via configuration.
I use exclusively Reaper for live mixing 16 I/O channels via USB3 (Zoom UAC-8 + 8 channels from another ADAT Pre-amp: Focusrite Scarlett 18i20 with USB disconnected).

After heavy treatment on windows 10 it is capable to run 32-Sample buffer at 44.1 kHz stable, but for live mixing I use 64 Samples, and if recording is enabled I use 96 Samples, just for safety.

The necessary treatments for no clicks in audio stream at low latencies:
In Device manager search ACPI battery: right-click disable it (yes it really interferes)
Set the power plan to high performance and check in details, if USB power saving is properly disabled.

The following steps are only for the fearless!

Use Windows 10 1607 with no updates (from pre-Meltdown-and-Spectre era)

Put these lines in a file like audiooptimization.cmd and run it as administrator before each live performance (some settings get reverted after reboot, only some remain):

From rehearsal to concert and after-show party you will run Reaper as live mixer with 64 Samples for 12 hours without any glitch or interruption or restarting any software. I wouldn't see the need for a desktop computer for this kind of setup.

For heavy VSTi-usage I would use a separate computer.
If you use other software than Reaper for syncing reasons, the Windows 10 treatments will be useful in the same way. MAC-users may be happy anyway (but not for too long: meldaproduction Email from Apple about Catalina)
