Sure Giana. ill give it a go, :)
the DAZ V3 Model runs about 60,000 polys, so its about the equal of 3 Vicki's when you have loaded all 10 models.

This model is broken into 10 different "props" so you can add or leave out certain pieces to save your system resources, the 2 higher detailed trees run about 20,25 thousand polys apiece. so just by removing those 2 reduces the poly count by a third.

each piece is not particularly large, its just that there are 10 of them, :)
and the file size is just over seven megs zipped up, i think all the files are around 20 megs unpacked.

i would say if you have a Pentium 3 800mghz or so and 512 mgs RAM you should be able get all 10 of them all loaded at once.

I hope this helped, :)
if you have anymore questions, please feel free to ask.
