System monitor app shows that ubuntu uses only one core 100% (constantly over 99%) and the other 7 are not used at all (0%) also -while one core being at 100%- checking on the processes tab (which I display all + dependencies) all the processes show 0% usage... so what is happening here? At first I thought there is some bug or incompatibility with the app..
but now after opening a few more firefox tabs or trying to do parallel stuff (like installing something while watching a video or what not) ubuntu windows freeze one at a time and unfreeze continue what they are doing including console...
So I guess System Monitor app is right and only 1 core of my cpu is used...

I have also a Nvidia GTX 650 Ti as a GPU
I have installed both AMD microcode driver for the CPU and the Nvidia driver.
