Haswell Xeon is way too outdated in 2022, but there are loads of newer ones. There's a fair inventory of Skylake and Cascade Lake Xeon on ebay, like HP Z4 G4 w/ 32GB and a GPU for ~$750. It's a pretty square deal considering. Since Ice Lake Xeon workstations are so thin on the ground, this is the most recent Xeon you can get second-hand.
The Ryzen story is a joke if you are actually in the market for a workstation, meaning you want ECC that works. The only way to get it is to buy integrated OEM workstations with the TR Pro.
