There is a huge difference between Poser 10 and DAZ Studio 4.7 for this market's content. Poser 10 is only 32 bit with the significant memory limitation that includes. If you are happy with rendering NVIATWAS images then that limitation should not bother you much, however once you want to add a bunch of things for her to use that sword on, you run out of Ram really fast. :) 

With full OpenSubdiv Support in DAZ Studio, the need for the, historically, high poly count of Poser/DAZ Studio Content pretty much goes away. 

I will also point out that asking the same question in the  DS forum, would probably have gotten you much different responses.
