The nice thing about GRASS GIS (and I think that not many other software 
packages have this), however, that many modules can be run using low RAM 
as well (see the raster modules with the memory option and the 
GRASS_VECTOR_LOWMEM environment variable). This allows to run complex 
analyses on large datasets with low levels of RAM. You just have to be 
ready to wait ;-)
