Don't know. I use Poser 6 (SP2) and my system has 4 Gigs. As soon as I have big textures loaded and other apps open I have to close the other apps. Also working with Photoshop (print) need tons of RAM. The support guy from alienware only said, that more than 6 gigs is useless because I work with XP Home edition. I also work with Bryce and Shade. And these apps are also hungry for RAM.
