I'm looking to upgrade my GPU because my current setup (i9-9900K, RTX 2060 6GB, and 32GB RAM at 3200MHz) isn't giving me the performance I want in modern games. I want to stick with my current platform for now since upgrading to a newer CPU would require a new motherboard and more investments. I'm considering getting either a refurbished RTX 2080 or 2080 Super, but I'm also tempted to go for a newer model from the RTX 4000 or 5000 series. My biggest concern is the potential CPU bottleneck with a higher-tier GPU—some calculators suggest it could be around 30%. What do you recommend as a good value upgrade to pair with my i9-9900K without wasting my money?

For your setup, the 9060XT 16GB is a great option. AMD cards have significantly lower CPU overhead, making them a good choice right now. Plus, they pack a punch and will boost your gameplay nicely!
Honestly, I wouldn’t trust those bottleneck calculators—they tend to be overrated. For a solid upgrade, consider the 9060 XT 16GB or an ARC B580. If you're gaming at 1080p, you might look at 8GB cards like the 9060 XT 8GB or the RTX 4060/5060. It really depends on what prices you can snag them at!
A friend of mine has a 9900KF with an RTX 4090 running at 4K 165Hz, and he's loving it. If you can afford it, I say get the best GPU you can. It might feel overkill now, but as games evolve, you’ll be set for the future. Just keep in mind, if "the best" means RTX 5090, it might make sense to upgrade your whole setup, so think it through before buying.
You mentioned your monitor—what are you using? That could impact your GPU choice a lot!

I have a 32-inch 2560 x 1440 165Hz monitor, plus two 27-inch 1080p screens. I mainly game on the 32-inch.
