PC for linuxcnc

I have used almost all of the older Ryzen processors, like 3500x, 3600, 3700x, 3900x, 5500, 5600x, 5600g, 5800x, 5900x, 5950x and 5500u and 5700u, all worked fine except one combo of 3500x with a good motherboard that for some strange reason had terrible latency.
As for overheating, the 7000 series heat up the most and they are programed to run at max possible speed until they get to 95 degree C, then throttle down. Meaning 7000 are the worst if heat is concerned, although they can handle it without issues, ever, but throttling down might cause latency spikes.
7000 series also uses AM5 socket/boards and DDR5 memory, all have higher prices, so right now i can get a 12 core 5900x system for the same price of the 7600x system with 6 cores.
