Yes I think your new machine will be more than adequate for years to come.
The temperature range of the cpu, I assume you are talking degrees C, seems rather high, I run my old machine around 50C but as you say for CXPU that is low.
I'm from the old era working with mainframes that had to be kept around 25C so I try to keep the CPU and GPU temps as low as possible. What is the norm for a CXPU chip?
