Best graphics card for Premier Pro?

After years with CS 5.5, my computer has died and I’m trying to figure out what to get as I move to Creative Cloud on a new Microsoft-based computer. The graphics cards completely befuddle me. I see Nividia is preferred for Premiere Pro, but which? Safe Harbor computers, where I bought my last, has a default recommendation of GeForce RTX 2060. Puget Systems’ is the RTX 3070.

Neither is on the Adobe list of approved items for Premiere Pro.

For what it’s worth, my source material is generally H264 or Canon MXF or still photos, and I usually export to H264, though I may want to get into 4K in future.

So – looking for advice on what graphics card to order. Any help greatly appreciated.
