I always wondered if that's worth it.
I've been running a whole band (16in, 8out) with Ardour, 3x Guitarix and "standard effects" (EQ, Compression, Barry's Satan Maximizer, etc) for some years now on a 10th gen i7.
That's with -rt patches and running live.
I considered switching to Xfwm, but even with Gnome3 I never had issues with performance.
I don't think its necessary for performance reasons, just a personal choice which one you like better.
