One thing I haven't seen mentioned in this thread.. what is the RPM of the hard drive? Most off the shelf hard drives for laptops are 5400rpm. A 7200rpm drive will make a difference on perfomence. For Poser 6 your low MHz processors will take awhile to render. One thing I learned a long time ago with software specs, look at the requirement then have a system that is either double or even triple those. From experince I found the minimum requirements are for installation but will the software actually do anything? Try installing WFWG (win3.11) under min specs, it installs but nothing else works properly until the RAM is increased.

I must remember to remember what it was I had to remember.
