i would say upgrade your harddrive and burn games as backups in case hd ever goes out... but with games on the hd, loading time decrease dramatically and it saves on your dvd drive for movies and so on... just my $.02 peace seamonkey420
Hard drive rocks. Store everything on it. Games,roms,movies,music,apps,porn,etc. And seamonkey already said the #1 reasons loading times are insane.
