And I have two intel MACs and no performance issues on either. I should try and install it on my daughters iMAC, but I know that is was tested on a lot of those, so I do not think it is the Architecture that is causing the issues for anyone with an iMAC.

Minimum System is just that... Someone running the minimum OS, with the minimum RAM, Video Card, etc.. (Bare Bones so to say) should be able to run the program. They may need to use minimal settings like Bounding Box, etc..., like I had to do on my old system when I first got Poser 5... I was so happy when that machine bit the dust...  The what it needs verses what it needs to perform at its peak has always been like that, but it is like that with all software. Vista does not require a lot of RAM, but runs a heck of a lot better if you have more.
