I really enjoy reading the Bitsquid blog (two guys who made a game engine and sold it to autodesk). They have a much more balanced take on the subject (eg http://bitsquid.blogspot.com/2011/12/pragmatic-approach-to-performance.html http://bitsquid.blogspot.com/2011/12/pragmatic-approach-to-p...) and lots of practical examples (eg http://bitsquid.blogspot.com/2012/09/a-data-oriented-data-driven-system-for.html http://bitsquid.blogspot.com/2012/09/a-data-oriented-data-dr... , http://bitsquid.blogspot.com/2014/08/building-data-oriented-entity-system.html http://bitsquid.blogspot.com/2014/08/building-data-oriented-...). There are benefits not just to performance but to clarity and debuggability. It becomes much easier to figure out where your program is spending time or where data is being corrupted because work is done in large, homogeneous chunks instead of being spread all over the stack trace.
