workstation graphics card

[Khaliis]

Im building a computer for a friend that is an interior designer and architect. She will be using mostly Autocad and rendering some pretty crazy 3d floorplans and whatever.
Can someone give me an idea on what the minimum requirements on a NVIDIA gpu would give me decent performance ?
Also , what would be the best possible GPU for this . I was looking at workstation gpu , the quadro and they seem really pricey.
Is quadro worth it ? or would i be more than ok with just a powerful geforce ?
what does linus use for his video editing. autocad and that stuff are pretty similar so i think what he uses should work great. tell me if im wrong

I believe that Linus uses either the Titan Z or titan X, i cant remember which one

I think the ltt team uses titan black cards

if he's gonna use only for autocad and not gaming.. I would say a titan x its a waste of money... get a quadro or a firepro, and dont probably you dont need the most expensive one......

the quadro and firepro are more expensive . they are workstation gpus . autocad does some serious 3d work so i want to make sure i pick something that can handle a heavy workload and render some crazy 3d floor plans no problem really fast
