Hardware for streamlines and contours in a 10^9 3D cartesian grid


I am preparing to purchase a workstation that will be used for Paraview sessions.
A typical dataset will be, for example, a flow in a porous material. Streamlines and 3D contours will be required. The size of the Cartesian grid is approximately 1000x1000x1000.

I’m wondering what hardware configuration is recommended for such tasks, regarding CPU, RAM and GPU.

Thank you so much !!!
