The world of upgrades is certainly changing and the days of complete new computer seem to have become questionable some time ago, unless of course your present PC has died and is uneconomic to repair.  I was recently surprised to find just how powerful mini PC are becoming and they are improving all the time.  The change to GPU rendering threw all the cards in the air and changed upgrade paths for good.  The good news it that there are so many solutions there should be an answer for every one and, in comparison to the old days, many solutions can be relatively cheap.

 

 

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.
