I'm pretty sure I tried it empty as well.  On one hand, it makes sense
that it only affects video type packages since those are mostly about
video stuff, right?  I'd never thought about it before.  I just always
get the info from that gcc command or the cpu flag tool and put them
in.  I never paid any attention to what packages it affected.

Since my mobo will be the oldest part, I may keep a eye out for a sale
on them, after the holidays maybe.  If I find one, buy it and just stick
it on the shelf in case I need it.  I replaced the power supply just a
few years ago.  It should be fine for a while longer.  Still, I may can
catch one of those on sale too.  ;-)  If I keep going with this, I'll be
looking for a case too. ROFL 

According to the tracking, my CPU fan should be here tomorrow.  That's
what I'm waiting for.  I got the CPU several days ago.  May get busy
tomorrow or Sunday.  o_O
