The Precision T3420 originally shipped with the 1270v5 as an option when it came out so that is a drop in upgrade. The 1270v6 (or other E3v6 for the matter) will however, a BIOS update is needed before it can boot so don't off that 1220 just yet. I assume you are running an external graphics card at the moment as the 1220v5 does not have integrated graphics. One thing to keep in mind is neither the 1270v5 or v6 have integrated graphics as well.
Based on the current going prices of 6th and 7th gen E3 CPU's (12/17/18/) you may want to consider a 1245v5 given the performance/price metrics. I just picked on up on ebay a just a few days ago for $180 after tax and all. I just did a quick search and found some local 1270v5's for $245 and up. The 1245's do find their way onto ebay you just need patience and a saved search with alerts on the ebay app.
EDIT: Upon further investigation I dont see any argument to prefer the 1270 over the 1245 based on benchmark scores on Userbenchmark.com or Passmark.com. They are so close that its 100% with the savings
According to Microsoft’s Windows 11 system requirements tool, the only factor my desktop does NOT meet in order to be able to run Windows 11 is the CPU. Microsoft’s list of the Xeons that do support Win 11 is LONG, but a Google search of which ones do work with my board produces no definitive results.
Can someone help me pin down which Win 11 compatible Xeons, if any, will work on this mobo?

I would like to swap the CPU with one of the following:
Intel Xeon E3-1270 v5 SkyLake 3.6 GHz LGA 1151
Intel Xeon E3-1270 V6 Kaby Lake 3.8 GHz (4.2 GHz Turbo) LGA 1151 72W
Is there any reason either of those would not work?
Thanks !
