I use Poser 8 exclusively for my 3D work. It seems to run pretty well on my HP quad-core system w/Win7 64 bit. It still has a few quirks (such as when I change a figure's pose, sometimes the hair and clothing don't follow the figure - reconforming one item results in all items snapping back where they're supposed to be..LOL).

I have DS3, but haven't had time to play with it much. I just DL'd DAZ4 - but I think I'll let the Cyberdoc figure out how to fix the bugs before I install it myself... LOL!
