Nvidia have drivers optimised for these later Pascal cards, so, yes, it'll be a good idea to update.
As JackNaylorPE says, disable Win 10 from auto updating first then:
Download and save the latest WHQL drivers ONLY from the Nvidia or manufactures site, but don't install yet. There is plenty of other places, but many are riddled with nasties, avoid them.
Uninstall the current drivers.
Power down the system.
Swap cards.
Boot up-note the display will be poor, you'll only be using Windows basic drivers at this stage.
Install the drivers you saved out earlier (they'll be in the Downloads part of Documents) using the clean install option.
Restart as required and be aware, the screen my go blank or flash during the install, it's normal, don't panic.
Enjoy.
