Everyone seems to have different experiences with Poser 5 baoling. I have a Pentium IV, 1.7 ghz CPU, 512 DDR Ram on Windows XP Pro and it still runs pretty slow. It gets slower as the number of products you add increases :) I would think your system would have problems handling Poser 5, but I guess it depends on your level of patience, what you plan to use P5 for and what other things you do on your computer :)
