I will use Blender, some Autodesk, i don't know at this moment, i'm just preparing PC for that.I'd suggest something along the lines of a 1660, 1660 super or 1660 ti, if you have the budget for it a 1070 is better and maybe 50 bucks more.
A 1060 though is good value and will be sufficient for rendering.
Also, what rendering engine are you using?
For something like Blender cycles definitely a 1660ti budget end and 2080 high end.I will use Blender, some Autodesk, i don't know at this moment, i'm just preparing PC for that.
