I have a ryzen1700 8 cores and an msi 1080ti GPU, 16gb RAM, ssd 960 evo 500gb (for running programs), seagate barracuda 3tb (for storage).
You could think, where would things possibly go wrong regarding of GPU memory for example?? Even my renders while crash sometimes.
I realised that, ok, a workhorse system is nice to have, but you really have to dive into your actual workhabbits.
– polygon count (get rid of polygons you don’t see, distance wise and for example behind an object
– easy on subdivisions, especially for objects far away or which get blurred anyway
– use renderlayers
– check your tile size while rendering (add-on Auto-Tile Size by Greg Zaal comes in handy)
– do you use textures with high resolutions?

Good luck!
