I agree with this, to a point.
When you use words like CAD in your 3D design, it changes the entire conversation.
You want to use Maya and Blender? Feel free to use a gaming card. You want to use a robust software like CAD, get a workstation card. Workstation card for a workstation software. If it was “well, it doesnt matter” conversation, then the biggest 3D developers (not gaming devs, 3D designers) would just toss in a 1080GTX TI and call it a day. They dont.
