I had the same choice to make when I first bought Vicky, option No1, or option No2. In the end I went for Vicky 2, from reading messages posted here by other members Victoria 2.0 (to give her her posh name) has more morph options & is generally better to use. You don't need a preliminary installation of Vicky 1 to install Vicky 2 (unless you plan to go via the upgrade path). I'm running a P3 500 mh with win98. With your spec you should have little trouble running anything you buy for poser. A lot of people hereabouts reccommend as much ram as you can cram in, poser uses lots when rendering (if you plan to render in poser & not lightwave, I don't know how ram intensive that is when rendering). People hereabouts are very friendly, if you need more advice just hollar!!
