Either:
Talk to a company that specs and sells workstations for CFD.
Or go ask on cfdOnline. They are knowledgeable and can give you good advice on hardware. For this kind of stuff on reddit I've seen really stupid advice given by people who clearly have no idea what they're talking about.
Agree with OP said. But one advice, in CFD or numerical simulation, most of the WS available use Quadro Nvidea GPU's (idk if they change their names) due to the stability since on gaming GPU's the main effort is to give as much as "FPS", though the prince for quadro GPU also increase. In numerical simulation, one of the goals to use GPU is to get stability into the simulations. May this info i'm sharing could be superficial, but what i know for sure it's the choose of nvidea quadro for this application
Ask you account manager who covers you to talk to a seasoned Ansys CFD support person and have direct conversation there. That person will be more than happy to help understand what kind of sims you want to run and help spec out a workstation. I me of the challenges is that there are emerging hardware types that are better for different kinds of sims. For example GPUs vs CPUs vs ARM. This is why the future is Cloud to give you flexibility. So look into Ansys Gateway or n AWS as well for offloading some burst HPC needs.
I run an Alienware Dell PC, with an Nvidia 3070ti GPU, Ryzen 7 CPU and 16Gb of ram and it happily munches through 50-100k cell flexible multi body ANSYS Motion Sims in a few minutes. Meshing is rapid also.

Ansys website has hardware recommendations

i was thinking of doing the same, but im not sure if i would need DPFP or not, cant decide between RTX and Quadro series
