When I was looking at prices a few years ago any Firepro was expensive but then I am based in the UK so that will have an impact on the asking price. 

Despite the supposed difference between the requirments for rendering or gaming I have never had a problem with running Poser and I have always used supposedly gaming cards and never more than mid-range.  Also when using the term rendering with graphics it should still be remebered that it is only the preview we are talking about it is not involved with the render unless you are using OpenCL which is a very different beast to OpenGL.

 

 

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.
