To me, it shows that Apple recognizes how miserable of a failure the Mac Pro 6,1(late 2013, aka the "trashcan") was/is.
With dual X590 CPUs and a couple of PCIe drives, my 5,1 will run circles in almost every way over even a top end, $10K+ 6,1.
Unfortunately, one of my primary uses for the computer requires that I run Snow Leopard on it. I need to run PowerPC-native software to interface with Firewire peripherals, and want to use that alongside Intel-native software. The fact that I need access to Firewire means virtualizing Snow Leopard is out for me. Also, there are not any Metal-compatible GPUs that will work in SL. That means I'm "up a creek" on Mojave. I'm running a 5770, and I'm hoping that Mac 5870 prices will tank now that the card is useless in Mojave-I may pick one up and enjoy the best SL GPU performance available, along with not half bad performance in High Sierra.
I haven't installed Mojave yet on my MBP 9,1(mid-2012 15" non-Retina) which officially supports it. I'm still running High Sierra on it. SO FAR, I've only installed it on my "backup" laptop, a MacBook Pro 9,2(13" Mid-2012 non-Retina) and it runs great on there.
Yeah, it is really quite remarkable. I did the CPU upgrade a few months ago as well, and that was dirt cheap to get into hex-core. WoW's runs awesome now, but is still unstable as heck on OSX unfortunately
