What are you talking about? 

System Requirements are here: http://www.daz3d.com/daz_studio

They have not changed. 

There is a Knowledge Base Article, where a Customer asked what the best system for running DAZ Studio is, and that one says things like 32GB of Ram will help, but it is in no way required. 

Thankfully my 6GB main box and my 4 GB notebook did not get the memo.
