While I don’t overclock my CPU or GPU, I still do want to know the utilization and temperatures, as these give me a hint as to whether the system is thermal throttled or bottlenecked.
I found that Oracle VM VirtualBox 6.1 was running very slowly on my brand new Windows 10 PC.

- The launch of next-gen consoles from Microsoft and Sony.
