The increased RAM will cause your computer to operate faster because it
will be able to temporarily store more information at any given time,
and this speed increase will cause your 3D CAD software to function much faster and with fewer “out of memory” errors.

This is basically all I know about RAM. Specifically regarding Rhinocerous 5 or 6, building large files that may be 5-7GB in size at time, with points, lines, surfaces, materials, animation (probably not a huge amount of meshing, not totally sure yet). How will Rhino use the RAM? Is a video card a substitute for RAM? Is Virtual Memory a substitute for RAM?
I need to understand more about how the software works on the hardware.
Thanks
