Will probably be buing a PS3 this weekend. However, some questions remain. The PS3 comes with a 500Gb hard drive which is used for demo games, save games and game installs. Does installing a game improve performance ? I don't mean FPS but at least loading times should be shorter. Can you install all games ? Are there games that you HAVE to install or can you run any game from disc ? Should I even consider the PS3 with 12Gb flash storage ? If these are such a bad thing, why is Sony even selling them ?
