My Poser PC has Win98 First Edition, an 800MHz processor, and 128MB of RAM. I have no trouble with Michael, and recently did a render featuring Vicky and Posette (fully clothed), George Deep's mummy, a complete dungeon environment, and some additional items for set dressing. On the other hand, my last render was of Vicky in the new trenchcoat, with Infernal's castle props, and it refused to render until I reduced the size of the coat's texture/bump maps.
