Most likely YES.

I am along time Poser user, since version 2. I tried DS3 but didn't really have any motivation to learn it properly as I had Poser.

I upgraded to DS4 and Poser 2012 since the cost of both upgrades was reasonable. Since then I have put some effort into learning DS4, and found I am getting more out of the DS4 upgrade than I did out of the Poser upgrade. Since upgrading both I have run up DS4 almost every day, Poser 2012 about eight times.
