I am posting this for a friend, yet I'm interested in the response
myself and will relay the answers to him. Adrian.

I have an upgraded 040 NeXTcube with 8Mb of 100 ns RAM taken over 
from the 030 board. Since then I have added 32Mb of 80ns RAM of 
(4Mb chips) filling the available RAM board giving me 40Mb.

My question:

Is it better to have 40Mb with 100 ns access
OR
Is it better to have 32Mb with 80 ns access

What are the pros & cons - I notice all new NeXTs run with 80 ns chips - ?

Thanks for your input,

regards,
