Consider your budget and needs. (LGA 1700)
I wouldn't buy a used 13th or 14th. Chances are, they have a lot of performance degradation. If you don't have enough right now... Just keep saving up. There's nothing here that screams you need to upgrade now . The PC still works. I'd say, endure it for a while longer.
Secure 12700k with no problems for the latest CPUs and at a reasonable price.
Used should be okay; the 12th generation likely experiences minimal wear. The exact amount depends on various factors.
