MongoDB ACID transactions vs RDMBS - Performance

Question

I am looking for some comparison between Mongo DB with ACID support vs RDBMS. I would like to see if Mongo DB with ACID can be a replacement for RDBMS for most of the scenarios. With earlier Mongo DB versions, the biggest gap between Mongo DB and RDBMS was support of transactions. A performance comparison (with transactions) would be a great help

Also as per the below article, 'MongoDB is not suited for complex transactional applications'.

The above is a generic statement and could be more useful with some scenarios
