My computer I built a couple of years ago
CPU – Ryzen 7 3700X 8 core 3.6GHz
GPU – Radeon RX 5700 with 8GB memory
RAM – 32GB
OS – Windows 10 64-bit
This I would consider mid range for Blender or CG in general. I think I am due an upgrade (my wife doesn’t agree).
I don’t generally have issues until I use physics such as fluid with a higher resolution, then I will hold my breath for a minute or two as things begin to chug.
What I didn’t mention earlier was cooling, I have 3 front fans pulling air in, and one rear exhaust fan, with a case with top ventilation (hot air rises), in addition to the CPU cooling, and plenty of space around for air flow. The higher the temp of your CPU, GPU etc., the less efficient it is.
