Hi :-)

As a general rule I would stuff in as much RAM as you can, especially with it being quite cheap at the moment. This can often make a big difference to graphic intensive programs like good ol' Poser.

If you get the opportunity, consider a faster processor too. I built my own machine, 1GHZ AMB Athlon T-Bird, 765MB RAM, and Poser whizzes along very nicely.

Hope this helps!

Dave :-)
