my shitty several year old ($200, second hand) Intel Core2 Q8200 2.33GHz w/4Gb ram, runs 3 screens, 2 browsers at a time with various extensions, both with up to 15 tabs open each (with at least one streaming something), paint, notepad, signal, vlc, minerd and word/excel running at the same time, and gets left on for weeks at time, only gets restarted when something is fucky.
performs perfectly well, i dig, i meme, i have baked with this machine. i do have good internet though.
tl;dr
$200, several year old pc, w/heavy loading, does good.
