Hey Andrew!
That's a solid system for design work and rendering. Of course you could go higher and get amongst the weeds on the finer details.
But in terms of having a very serviceable device that has some grunt it ticks the boxes.
Personally I'd go 4080 on the GPU. If they have an option for 4080 make sure your PSU is 750w as the 650w won't do.
Otherwise its a good build that's more than adequate to do 3D work and rendering.
