   That is usually not necessary, as long as the new proc+mobo are binary   
   compatible with the old ones.   
   Rebuilding everything is rarely needed, and, even in those cases, you   
   usually don't need to do that all at once.   
   For example, some critical upgrades (eg, /some/ gcc upgrades) require that   
   you recompile everything; in that case, the docs tell you to do so, and   
   that is usually accomplished by issuing an "emerge -e world" and let it do   
   its job (may take hours however).   
   Another common case is where you change your CFLAGS (as you probably did   
   after changing cpu and mobo). However, if old binaries run fine, you don't   
   need to recompile everything at once; instead, each new package from then   
   on will be built using the new CFLAGS, and, after some time, following   
   portage's natural activity (upgrades, etc.), you will have recompiled   
   almost all your packages.
