 If you want =

 CPU_FLAGS_X86 is not empty by default=2E It contains sse and sse2 by=

 default, because these are supported by all 64-bit CPUs=2E


 What I did, I commented out the whole line and ran it that wa=

If you comment it out, it will have default values=

empty string, you should be able to see which pa=
ckages make use of the
default flags (like sse and sse2=2E)

Note =
it's a pretend emerge (-p)=2E Just to check which packages you have
inst=
alled that make use of these flags=2E


One last question for anyone who has done this recen=
tly=2E  When finished,
I'll have a FX-8350 CPU with 8 cores at 4=2E=
0/4=2E2GHz, 32GBs of memory all
on a Gigabyte 970 series mobo=2E  W=
ould there be any point in upgrading to
a whole new rig or is what I hav=
e about as fast is reasonable to build?
I don't do gaming or anything=2E=
  Even the GTX 650 video card is likely
overkill for what I do here=
=2E  The older 200 series card is working just
fine=2E  On one=
 hand, my current build is several years old=2E  On the
other, comp=
uters seem to have reached their peak=2E  I'm sure there is
more po=
werful systems out there but would I be any better off with one?

Since the AM3+ and its C32/G34 Opteron counterparts =
are the last and
best x86 cpus without ME/PSP I would say you are better=
 off with what
you have - the best piledriver cpus like the FX-8350+ are=
 still able to
play the latest games and in a VM via IOMMU-GFX if you wa=
nt=2E

In any case I would consider a OpenPOWER (ppc64/ppc64le) arch =
system
(like the blackbird or talos 2) as an upgrade path instead of any=
 futher
x86 stuff as there aren't any black boxes, there is
documenta=
tion+firmware sources and the cpus are made in usa=2E


Made in USA isn't necessarily a good thing whe= n talking about not wanting any hidden back doors=2E
Not sure which coun= try would be a reliable location though, I wouldn't trust Western European = countries either=2E
