What is the use for the desktop machine? Are you going to do some more
heavy multitasking? Then the quadcore will definitely improve
performance. If it will be a simple desktop for mail, some surfing and
the occasional letter then the backend can definitively beter use the
parallel processing of the quadcore. Downscaling of processor speed is
automatic in most distributions. Set it to on-demand and it will
standardly go to the lowest speed per core unless needed. The
possibilities for downscaling are probably better with the quadcore.
