If the new card is supported with the 470 driver then I would replace the card while the 470 driver is running.
Then do the upgrade.
As I noted earlier, Roger's suggestion did show the new card was supported by both the old 470 and the 525 driver though the 525 is preferred.
So I shutdown the system, did the annual dust removal, and removed the old card -- learning that PCIe x16 slots have a latch.
Inserted the new card -- decided how to handle the switch from 2 6-pin power plugs to one 8-pin plug, and closed things up.
Press the power switch - nothing. Turns out while handling the case I flipped the rear panel switch -- whew!
System booted, graphics seem fine. Did a dnf update and rebooted. Used dnf to remove all the 470 driver bits including dependencies. I figured the in-use pieces would continue functioning, just disappear from the directory structure.
Then I added the 525 driver bits, the dependencies, and rebooted. Took quite a while (for a system that normally reboots quickly). I assume that was akmod building the driver.
But the system did come up, graphics again seem normal. System temps dropped about 2 degrees though the new graphics card runs a bit warmer, 37C vs 34C. Fan speed is lower, probably due to the dual fans vs single fan on the old card.
So thanks for all your input. Swap was essentially painless.
