Ready to upgrade - which version of Pro Tools?

[Tubthumper]

Thanks to everyone who chimed in on my recent thread re: upgrading from Pro Tools 11.3.1 on Win 7 64 bit.


I've upgraded my PC, now running 16 GB RAM, a new 500 GB SSD (system), upgraded (second hand) silent graphics card.


I've cloned my current system drive and will remove that and keep it as a backup in case something goes amok.


I've decided to do a clean install of Windows 10 64 Home. I watched a video posted on YT by "jayz two cents", he runs through a fresh Win 10 install procedure from scratch using a USB flash drive.


Now, just deciding which version of Pro Tools to upgrade to - I bought a Reinstatement license, I believe that gives me access to the current release, and all previous releases.


Just wondering, have there been any standout Windows versions of Pro Tools released in the past year or two? Standout meaning reliable, stable, not overly resource hungry, good feature set.


Or should I just upgrade to the latest version?


Finally, is an NVidia graphics card essential, or can I get by with my second hand Asus Radeon HD6450 500 MB card?


Thanks.
