Can I ask what sort of rendering you're doing? Do you mean animation or still images... what software? I find that between different software you can get vastly differing render times. Also, for really serious and large work aren't people using render farms now anyway?

Doing animation and still (admittedly haven't produced anything yet as I've only had this setup running for a week) mostly motion graphics and advertising focused.

I'm working in Cinema 4D and Octane render (render engine built from the ground up for GPU) with a single GTX 1080, coming from a 2.7 i5 MBP with no dedicated GPU the difference isn't even comparable.

Good idea of what you can expect from a single 1080+Octane is in this video https://www.youtube.com/watch?v=jGXmsUnbPCM

The industry is at a bit of a crossroads from what I can see, of course huge studios have investments in render farms and CPU based tech but for individuals and <10 person studios it's all moving towards GPU rendering.

Being able to run a renderer on your desktop machine that can show the end result in near real time completely changes your workflow. It's no longer just using experience to make guesses with lighting and materials then waiting minutes to see if your hypothesis was correct.

Thanks for info. Yes the live render previewing is getting quite nice.
