> "...GTX 1080 + 980ti..."

What can I say ?
....both extraordinarily powerful GPUs!!! (..and much much expensive....)

But, I must admit that I love Quadro cards because they're unreachable when we talk about precision and speed for CAD modelling.
Even if they're not so powerful in DirectX PBR as GTX and Titan cards.

I hope that within a couple of years I can save some money to get a brand new Quadro card...but it's hard to say :)

Best,
