Every time I want to move forward with anything, it means I have to spend $.
How did I know it would apply to this situation as well ! Don't tell anyone I'm still living in the computer dark ages, it's a little embarrassing. I was probably one of the last people clinging on to Windows XP until it finally was no longer safe, squeezing every last kilobyte of life out of it. This is a recurring theme with me because I'm just too lazy or cheap or a combination of the two. :-)
You could do what I did in 2015: Pay a boatload for the best customized laptop available at the time, with the goal of being "futureproof", and then use that until the world finally catches up to it.
$6k for a Dell Precision M6800 with all the options checked and maximized, and it still does quite a good job today. It came with Win7 (option for Win8: NO!), I dual-booted it from the beginning between that and
Lubuntu Linux, upgraded both several times, and eventually switched entirely to
Ubuntu Studio when Win10 decided that it wasn't going to to update anymore. It would try, and always fail. Googled a bunch of solutions, none of them worked, so now my Windows side has all of its networking disabled in case I do run it, but I rarely do anymore.
It's still my daily driver, and I'm presently using it to work out the intricacies of a live meeting rig, as a test machine that might actually run a few while the main one gets overhauled to do the same thing. Two copies of OBS, both in Studio mode, 1920x1080p30, and a DAW to do all of the audio with a surprising amount of processing and complex routing for what it seems to be on the surface. Most of that is to make it all automatic, so that the presenter works as if they're just producing a single live stream, and even that feels more like PowerPoint than a TV studio. Those scenes have a naming convention so that the
Advanced Scene Switcher plugin can reconfigure things according to what's happening at the moment.
All of that on this so-far-futureproof 8-year-old laptop, and Ubuntu Studio's CPU load indicator is around 30%. All 8 cores roughly even, and using 6GiB of RAM.
