Dresden city card includes admission to all museums except Historisches Grünes Gewölbe in the Residenzschloss. I would recommend in order: Neues Grünes Gewölbe in the Residenzschloss, Gemäldegalerie Alte Meister in the Zwinger, Türckische Cammer in the Residenzschloss, and Rüstkammer (Armoury) in the Zwinger. Overrated are: Porzellansammlung in the Zwinger, Galerie Neue Meister and Skulpturensammlung in the Albertinum. I would visit again if they change policy to allow photography w/o flash.
