Hi,
Are you a full time professional?
In the meanwhile and according to Puget..
The processor (or CPU) is one of the most important pieces of a Photoshop workstation. While GPU acceleration is gaining traction, right now your choice of CPU is usually going to make a much larger impact on overall system performance
I believe you are pretty safe with the 6750XT unless you do a full time job and time is money.
I'm no professional, but my personal take for video edit is RX6800 at least.
Good luck
The Englishman
