well i was just wondering how much energy an average gaming computer with a gaming gfx card in it uses in a day.
I'm not sure if this will do the trick, but try: http://extreme.outervision.com/psucalculator.jsp Never tried it myself so no idea how reliable it its. There was also this website that took into account your computers components and told you how much energy it used, can't find it now though. Maybe someone else can?
