That card will work fine for working in Poser but of course wont improve rendering speed as mentioned above...  However the better your video card displays the preview the more likely you'll be able to get away with rendering in preview mode and that would be a heck of a lot quicker!!  Been meaning to test it out today but am heading out soon for New Years Eve frivolity!!!

You are pure, you are snow
We are the useless sluts that they mould
Rock n roll is our epiphany
Culture, alienation, boredom and despair
