My 5.1 one sessions on an HDN card are getting larger over the years and with the plethora of CPU hungry plugs over the years, I need way more power. My main OS is on an SSD on 10.12.6 and recently upgraded to 2018.12 from PT11. And with 2019 with 384 tracks... well will need every ounce of power I can get out of the Mac.

The options I am looking at:
1) upgrade CPU to 3.46GHz?
2) upgrade ram to 6 x 8GB sticks (getting faster triple speeds?)?
3) upgrade to a XFX RX 580 GPU?

Any of your opinions or reviews from personal experience would be greatly appreciated on which route to go with and how much it can help.

As I am sure this will help others too.

I upgraded my MacPro 5,1 to 12 core 3.46GHZ and glad I did. Much smother performance with Pro Tools 12 and above (12 is when things stated to get slow).
