I think it's never a waste to get more education. But getting an advanced degree from a mediocre school for the sake of career advancement probably doesn't worth it. A few exceptions: 1) You want to learn something but doesn't want to go through the 90-credit undergraduate. In my university they give you access to a CS graduate diploma that consists of 10 core CS courses under the requirement that you already have an undergraduate degree (non-CS) and pass the entry CS course about programming (usually a Java 101 course). IMO it's a LOT better than a 90-credit second undergraduate degree on CS. The other exception is that you want to do the research but I'd argue it still doesn't worth it unless it's a prestigious school like top 20 in North America (MIT, Stanford, CMU, Waterloo, those top schools).
