Like 8GB ram with 1 TB HD. But it depends on ur like if u need to be app developer u should have atlist more than 8GB ram b/c android studio need more ram. . Or if u need to be web developer still 4GB of ram is also nice, Also if u wanna to be graphics designer or game developer u should have to buy pc which have more than 8GB of ram. But it depends on ur income and ur interest.
