Is it necessary to update bios? I do have a 3090 FE GPU. Intel - 10900K. I see so many different versions you can download for bios updates. I don’t have any issues with my current version bios. The bios I’m using is back in 02/04/2021. So is it worth updating.

We don't need to know your GPU or CPU, we need to know your board model.

In general, today's motherboards are "bananaware" that ripens after it's sold, in the form of BIOS updates. I have explained it all a bit more here. The first release BIOS that the board ships with is usually pretty buggy, and they fix the biggest bugs early on, from all the early user feedback they get about them. The latest BIOS updates tend to come a bit less important. But it's not just bugfixes or feature enhancements, it's also new Intel microcode (exists on AMD too, they call it AGESA). New microcode not only adds support for new CPU models, it's basically a code update for the CPU where Intel can fix errata and security holes and even add/remove/change certain CPU functions.

So i would say, you don't want a BIOS that is too close to the earliest version. This will still have a bunch of bugs. Once you have a BIOS version that's five or six updates in, you ideally shouldn't suffer from the worst bugs anymore and have a halfway recent microcode revision. So then you can check for the features they add. For a lot of older boards, they added Resizable BAR (Re-size BAR), which grants direct memory access to your graphics card and is free added performance without any downsides. So that feature alone is worth updating for.

The Intel-based boards where i would definitely recommend updating to every single new version (even the beta versions) are the boards with the 600-series chipsets (and to some degree 500-series).
Not only is a BIOS update often practically risk-free there (because of the Flash BIOS Button as a safety net), they are also newly developed platforms that had a lot of new BIOS code for the first time.
In the past, the technology was extremely similar since 2015 (see timeline), but with Rocket Lake and even more so Alder Lake came two bigger changes, with immature BIOSes at release.

My opinion differs.

I'm more of the mindset, if it works fine, why change it unless you have a specific reason to?

All too often, we find that the new BIOS update breaks something. And then you have to go through the painful process of undoing it, and (with some searching) you can find that just flashing the old bios may not fix it again......

More or less anymore, my opinion? Unless the update you're flashing to fixes a specific issue you're seeing? I wouldn't bother.

I don’t have any issues with my current version bios.
The young generation: "Be always up to date"
The older generation: "If it ain't broke, don't fix it"

Question: did you ever see a wise young guy?

I'm not that young anymore. I've always kept my BIOS and other people's BIOS up to date. Must've done it over 200 times perhaps. Most of them went smoothly, without any problems afterwards.
Perhaps a handful i had minor problems afterwards, and only two caused bigger problems. But today the risk is so low once you have the USB flashback feature.

Thank you for the thoughtful reply! After updating to a new BIOS, do I need to reinstall things like motherboard drivers? Or does one just install the newest BIOS and call it a day? Thank you!

Generally, just install the BIOS.
In a few rare cases, you may need to update drivers, etc.....It really depends. Check the instructions with the BIOS to really find out. Usually they mention that.

I would generally be of the opposite opinion......if not for the crap that the Ryzen series of CPU's has gone through over the past few years. Since it's release, it's been a complete shitshow for BIOS's. Some work great, others, you're better off not upgrading.
And in some cases, even with Intel, the security breaches are kinda meh.....Like, I get that they're important, but lets be honest here. If someone wants the info or whatever is on your computer.....they're gonna get it. And those breaches are so particular, it's like driving a F1 race in order for it to work, and honestly, they're not going to be targeting normal people with it. They'll be targeting corps and others that have information/intel/things that are worth selling. And usually the Intel ones have some amount of performance penalty associated with them, which makes them even more unappetizing.
