The graphics card does not matter much, since Poser does not use it anyway. I would think that the RAM is more important than the processor speed here. Get enough RAM and you can cope with a processor close to the minimum spec. The dynamic hair, the procedural shaders, the FireFly renderer in Poser 5... They all eat RAM! I also believes that the OS plays a major role here. An OS with good memory handling (Win 2000/XP) can take advantage of the RAM and compensate for a slower processor in a way that Win 95/98/ME never can do.
