I'd suggest CFLAGS="-O2 -march=i686 -pipe -fomit-frame-pointer"

	CXXFLAGS="${CFLAGS} -fvisibility-inlines-hidden"

	MAKEOPTS="-j2"

If you wish to have latest packages, change ACCEPT_KEYWORDS="~x86", it
might make your system a bit unstable but going through my experience it
has not broken a thing in my system.

Also if you wish add these lines to /etc/make.conf

	LDFLAGS="-Wl,-O1,-z,now,--sort-common"

Do you really need all these USE flags and features? I think not.. Add
USE flags that really are useful not add them just because they might
become useful sometime.. The more features you have in your packages,
the slower and more memory hungry they are.. Take a look at my USE
flags..

USE="-X -arts -apache2 -berkdb -cups -dri -eds -esd -gdbm -gnome
-gstreamer -gtk -gpm -xmms 3dnow acl bash-completion bzip2 fbcon hal lzo
mbox mmx nsplugin nvidia offensive sse svga tiff urandom"

-X because I don't every application to be built with X support, -arts
because of the same reason.. The applications that i think will need X
support I add a line like this to /etc/portage/package.use

	media-libs/imlib2 X

Also if i need to remove some support from packages, i add line like
this to /etc/portage/package.use

	www-client/links -jpeg -png -sdl -svga -tiff

I also don't suggest hardened USE flag.. You most certainly don't need
them.. Trust me..

Add these lines to /etc/make.conf to further fine tune tour system..

	VIDEO_CARDS="<your video card" #like nvidia, ati
	INPUT_DEVICES="keyboard mouse" #add anything extra you've

Remember, always add the minimum USE flags you need to /etc/make.conf,
you should always tune your system to specific packages by adding USE
flags to be used for the specific package to /etc/portage/package.use
