It was a waste of money. I should have bought booze and gotten something out of it.
I ran it and now mediaplayer is 24-42%. x2 higher after it did some memory tuning. (or some other improvement it dig)
But why does graph say so much more? Idle task is 100% - mediaplayer - maybe 5-10% (taskmanager and explorer. (Shell?))
Anyways. I'll prefer tuning the new pc when it arrives. Thanks guys.
