Yes, youll see a good increase in games and a little in desktop, but only a little. Now if you over clock the opteron 146 like mine, youll find your pc runs a whole lot smoother and faster. Even my desktop is just less laggy.I am running mine at 2800mhz, which is a 40% overclock. My games,utils,programs all run a lot better.I cant believe the difference in my pc now since i have overclocked it.
