The E8400 is a 2 core, 2 thread 65W CPU with a top speed of
3GHz. It came out in 2008.
An AMD Ryzen 5 3400G (4 cores, 8 threads) is $150; a low-end motherboard
is $70; 16GB of RAM is $100.
The resulting machine would be more than twice as fast on
single-thread tasks, and could handle four times as many
processes at that speed. Officially it would draw the same 65
watts, but AMD's calculation is for the maximum draw over a long
period of time whereas Intel's calculation is for the normal
draw over a long period of time; you should expect the AMD to
run cooler and draw less power for the same workload.
In the meantime: make sure the system is free of dust; make sure
that fans are running; make sure that the airflow makes sense to
bring air in on one side, across the CPU and RAM, and out on the
other side.
