I have an AMD desktop machine that I use primarily for gaming. Some days, I will play a game for an hour or so, then wait a few hours and then go back and play some games a little more. Is it better for me to turn the computer off while I'm not using the computer or leave it running while I'm away for a couple of hours? I know that leaving it on will require more electricity so that is a negative.. Any thoughts would be appreciated! Thanks!!
