...your model is certainly not even close to ac3d's limitations on your hardware.
At least on Mac AC3D will only address 4GB anyway (32bit app).
8GB do help to get the OS and other apps out of the way though
Have you tried updating graphics drivers?
Reducing some rendering options (anti-aliasing, et al)?
Maybe someone with better WinXP skills knows more.

Thanks again for the interest.
