Funny - I use almost every day a 2009 Mac Pro with a Sonnet 4x nvme card. It boots perfectly well Mojave, Windows 10 and Haiku.
64GB RAM (triple channel), and a Vega 64. I was playing Cyberpunk with 30fps lock at 2560x1600. It never makes me wait for anything, and it does fine 4K video editing without proxies with the correct version of Final Cut Pro.

I find quite insane that a machine that can take 1.5TB of RAM is going to be considered obsolete soon.

I never managed to justify myself changing the machine. There's endless power up there provided by our big fusion reactor in the sky, but materials are finite.
