  I would boot with install ISO or rescueCD, chroot, make the necessary
changes and then "emerge system" and "emerge world".  The necessary
changes are...

1) CFLAGS.  I use...
CFLAGS="-O2 -march=native -mfpmath=sse -fomit-frame-pointer -pipe -fno-unwind-tables -fno-asynchronous-unwind-tables"
CXXFLAGS="${CFLAGS}"

2) Check your USE flags (in both make.conf and package.use).  I have an
older Dell with an Intel.  I have "mmx mmxext sse sse2 sse3 ssse3" USE
flags.  AMD cpus benefit from "3dnow 3dnowext" and possibly other AMD-
specific flags.
