Playing back an MPEG video is essentially trivial load on any modern machine.

A pokey old
threaded code have hit an insurmountable bottleneck. There is a sweet
spot for the amount of ram and fast disk. If you put it onto a UPS and
enable all go faster options for the SSD cache write through (risking
potential data loss if power is ever lost) you may get some improvement.
You would have to decide if the speed gain is worth it to you.

things left are games and Spice.
Well, Spice is sort of a game too.In the sense that it is a simulation of reality.
There might be an advantage in going to 2 or 3 cores for some problems depending on how smart its use of additional cores actually is but after that you run into memory and/or disk bandwidth problems pretty quickly.If you check LT Spice on various CPUs I think you will find itEnabling more cores doesn't help much. What does seriously help -
correlates closely with ram speed and single thread performance on CPU
related benchmarks (obviously with a bias towards floating point code).
sometimes 20:1 - is relaxing some of the sim parameters. I do that
until something obviously breaks, then back off a little.
