I have delays when opening single sheets whith a mixture of loads of 
graphical elements and lots of text frames. But it takes ages, when I 
want scribus to compile them into a 50 sheet document.
Thank you for your attempts to improving the source.

This is good information, so next CPU will propably be a fast dual core.

I noticed before, that it jumps above 1 GB when it gets up to 40/50 pages.

This is something I would realy like to know, as my integrated graphic 
chip isnt very potent - and it uses RAM memory.

Yes... I think I will wait at least about a year with the option of 
installing a ssd. I am sure prices will decrease and they might get even 
faster.
Has anyone else experience with ssds and scribus?

Thank you again for sharing your experiences and your knowledge.
Personally I will still wait with updating my hardware, because the 
delays just happen when im sticking together big files.
Its just that for the future I would like to know what increases speed 
best.
