Yes, provided it has the necessary backwards compatibility (like the original 60GB PS3).
no. hard disk has nothing to do with grapihcs. but a 20 gb playstation has less features than a 60 gb playstation that's because the company made it like that. hard disk is just concerned with sroteage.
i need a playstation3
To download games to the Sony Playstation3 go to the Playstation3 store that is located in the menu. Choose the game you want and click on cart and check out. You will pay at this time unless it is free.
if you want it cheaper, get the 60gb, but with 60gb you dont have everything the 80gb has. however if you want all the features, get 80gb you decide, but i recommend the 60gb.
