I'm using Poser 6 on a 1.8 gig Intel 4 with 1 gig of RAM and a GeForce MX4 card. I guess we could call the specs fairly comparable with the exception of the RAM. I would recommend bumping it up to at least 512, more if you can. P6 is indeed an improvement over P5. But you might want to hear from others who have comparable system specs before you make a decision! Good luck!
