Depends on how much trust you place in -jX for X>1 and in my case, not much, yet. 

I am not in a rush, I have a few machines that take well over 168 hours to do a bootstrap and then a testsuite run. To me it is just a process sitting on a back burner simmering and I am fine with that.

As a fine example .. we have a testsuite run which just completed on this 2.6 GHz Opteron like so : 

    http://gcc.gnu.org/ml/gcc-testresults/2012-12/msg01762.html


sedna $ /usr/bin/time -p nice -n +19 gmake -k check 
.
.
.
real 23347.63
user 14833.37
sys 7920.38

Six and a half hours on a 3 GHz Opteron. Not pretty but it works.

ps : scary that it takes that long when I have two of these on RHEL 6.3 :
