Nope. BIOS updates are typically fixes for some issues, not performance improvements. If you’re not experiencing any issues, don’t upgrade as you can run the risk of bricking the card if something goes wrong during the update. Drivers are where performance improvements are.

Is it worth to update BIOS?

So yes, it is worth it right now to continue to update your BIOS when the company releases new versions. With that said, you probably don’t HAVE to. You’ll just be missing out on performance/memory related upgrades. It’s pretty safe through the bios, unless your power flickers out or something.

Does GPU affect BIOS?

It is the stuff you see when you go into the ‘setup’ sections of your motherboard while booting up to change clocks, RAM timings and other settings.
