My system, a few years old now, is based on a AMD Ryzen Threadipper 1950X CPU which was one to the quickest around at the time that was in my price range.  I am not sure that the motherboard supports TPM 2.0 but I do know Windows 11 does not support the CPU.   I am not a Windows hater so will move to Windows 11 when I have to change the system, or maybe even Windows 12 by then, but I am not dumping a working 32 thread CPU just for the slight improvements of Windows 11, assuming there are any. 

 

 

I use Poser 13 on Windows 11 - For Scene set up I use a Geekcom A5 -  Ryzen 9 5900HX, with 64 gig ram and 3 TB  storage, mini PC with final rendering done on normal sized desktop using an AMD Ryzen Threadipper 1950X CPU, Corsair Hydro H100i CPU cooler, 3XS EVGA GTX 1080i SC with 11g Ram, 4 X 16gig Corsair DDR4 Ram and a Corsair RM 100 PSU .   The desktop is in a remote location with rendering done via Queue Manager which gives me a clearer desktop and quieter computer room.
