I’m surprised to hear that. I’ve always understood SU to be a single thread, CPU driven program.
At which later version did this change?
I see that DaveR is replying, so I will add that a good GPU is essential also. For smooth orbiting, zooming etc.
The 9900K CPU is overkill, rather go for a 9700K (4.9GHz) if you’re Intel inclined, then apply the money saved towards a better GFX card, depending on your workflow (and scale of work) the nVidia GeForce 1050Ti might not be the best choice, see if you can hit a GF 1070 at least.
Unfortunately the 9700k does not suit me for other reasons (Vray CPU rendering loooves as many threads as it can have and 9700K only have 8) but with the information you all gave me I will make sure GPU is a priority of sorts.
the computer I am writing this on has a GTX 1070 and you are all right SU 2017 smashes the graphics card when moving the camera
the new AMD Ryzen 7 3800X delivers nearly the same multi-thread performance and a much better single-thread performance additionally being roughly 100 bucks cheaper and consuming 75W (= heat = noise) less.
