We learned this lesson the hard way. We got two very nice gaming PCs donated to the team last year to use for CAD. 32gb RAM, quad cord ~5GHz CPU, 512 GB SSD, good graphics card, etc etc. It is significantly faster than the computers in the school’s robotics lab, but it still freezes every few hours. When you check the task manager, one of the CPU cores is running at max speed while the other three are doing almost nothing.
Edit: I’ve been informed by one of my students that they actually have a Ryzen 7 3700X processor (8 core 4.4 GHz) and Ryzen 7 3700X GPU (8GB VRAM)
