After you hit level 60 in Diablo 3 you are thrown to new level system. It is called Paragon Level. The maximum paragon level is 100. Every level grants you 3 main attribute points, 2 vitality points and 1 to rest of attributes. Main attribute for Witch Doctor and Wizard is Intelligence, for Monk and Demon Hunter it is Dexterity and for Barbarian - Strength. But that's not the only bunus you get for level up. There is also 3% to Gold Find and 3% to Magic Item Find.
