cr.yp.to's site has great advice.   He reccomends going with a dual-cpu. 
I'm wondering if any of the GRASS components are written to be 
multi-threaded, to take advantage of such a machine.  For example, my 
underpowered machine has been r.patch'ing together 8  60MB rasters for 
the last 5 hours, and is about 50% done.  Would a dual-cpu machine get 
it done twice as fast?   While it is using 95% of my CPU, it's only 
using 9% of memory.
