Hi. I bought an i3 3220. I used to have a phenom ii x6 1045T but for economical reasons I had to sell that computer. Is it normal that my new computer feels so slow specially when I'm doing several things at the same time (like web-surfing + watching a movie(discontinuously) + word + matlab) I only feel my new computer faster when I'm playing videogames. Should I be worried? thanks.
