I used to use the bogomips number as a rough guide.  Thing is, the new
CPU has a lower bogomips number than my current CPU does.  That doesn't
seem right.  So, I guess that number no longer means much.  So, I went
digging on the site you linked to.  I found this but not sure what to
make of it. 

https://openbenchmarking.org/vs/Processor/AMD+Ryzen+9+5900X+12-Core,AMD+FX-8350+Eight-Core

Some tests, my CPU is faster.  Most, the new one is faster.  Some by
quite a bit.  It seems most things would improve but others may not.  Am
I reading that correctly?  I'm trying to figure if I'd be better in the
long run to buy that expensive CPU or pick one of the cheaper ones you
mentioned.  I started off with a 4 core on current rig and went to 8
core and slightly higher frequency.  Money wise it was pretty painless. 
I could do that again with new rig.

Once I pick a CPU, the rest will come easier.  Mobos have to have the
right socket, then it has only certain memory sticks that will fit etc
etc etc. 

Thanks for any light you can shed on this.  Googling just leads to a ton
of confusion.  What's true 6 months ago is wrong today.  :/  It's hard
to tell what still applies.
