I don't mine on them anymore, sold my dual 2011-3 setup that was my main pc after I built my 3700x/x570 pc.

Currently I have a socket 2011 dual Asrock Rack board with two Xeon 2620 V2's that run Proxmox that I run Windows 10 and Linux VM's for my wallets.

Mainly so I do not have all my wallets on one "pc" but spread across a few vm's so if something bad happens I wont lose all my downloaded blockchains for all my wallets.

I install two or three wallets and full block chains per VM.

I'll upgrade the 2620 v2 cpu's when the more powerfull v2's get a little cheaper.
