I ran up to Catalina on a macpro3,1 using the DOSDude's unsupported macOS installation kit? i didn't try to update to Big Sur on that workstation, I slid over to a 2013 trashcan6,1 and I should have bought a 7,1 instead of trying to make that thing work for me.
The GPUs you use matter, my 3,1 had a couple I used that there were drivers for in macOS; no more Nvidia web drivers but I got a GTX 680 and it wasn't great but it was better than a 5770 or something.
