To be honest, I can still do most of my work on my old Core2Quad 4GB DDR2 PC, when using Linux.
And as long as I setup my swap properly, I can also keep as many Firefox tabs open as I want , as I tend to forget tabs (running out of brain memory) before I run out of RAM.
But I just like my 64GB RAM.
But not with the default option of using as many threads as there are CPU cores.
