i got told that all the game for the x box 360 only perform to 33 or 40 % or somthing like that and when the ps3 comes out they are gonna start producing higer quality games .

That’s not true at all. Its really not that difficult to push the 360 or the PS 3. They both only have 250MB of ram. There are some games like Just Cause that will show off the 360’s untapped potential but we are talking the same improvements consoles normally have after the first batch of games.
