I recently upgraded my graphics card from a 2080 Ti to a 5080, but I'm noticing my 12700K CPU seems to be struggling at 1440p. In some games, my GPU is only hitting about 75% utilization, and it feels like it's not being fully utilized. I'm curious about switching to the AMD platform, but it seems too expensive right now after my recent purchase of the 5080. I'm considering upgrading to a 14900K instead, which seems to be a relatively affordable option given I might sell my 12700K for around 200 euros. I have a solid Asus Z690 Hero motherboard, and I know about the potential CPU degradation issues that have been addressed with BIOS updates. What do you all think? Is making the jump to a 14900K worth it?

You should definitely check your CPU utilization while gaming; sometimes the CPU can be the bottleneck instead of the GPU. Also, keep an eye on the RAM; it could be holding your performance back, especially if it's not at a high speed for the latest games. Just remember, the 14900K runs hotter than the 12700K, so make sure you have a solid cooling setup ready.
I think your 12700K is likely bottlenecking the 5080. If you're able to get decent resale value for your current CPU, going for the 14900K might give you a performance boost. That's especially true considering there are new Intel CPUs like the 1700 series coming out soon—might be worth the wait if you can hold off.
I didn't even know more LGA 1700 CPUs were coming out! I hope Intel doesn’t pull another confusing upgrade cycle like they did from 7th to 8th gen; that could complicate things.
You definitely want to make sure you're using good cooling with the 14900K since it can run pretty hot. If you have a solid 360mm cooler left over from your 2080 Ti setup, you should be just fine with that.
Right! It sounds like cooling shouldn't be an issue for you, especially with that 360mm radiator. Just grab a good CPU block, and you should be all set.
It's all about the games you play. At 1440p, a 5080 should manage well, but not every title maxes out the GPU. Maybe consider your current game library and see how they perform. If you’re running into CPU issues in demanding games like Fortnite, that could be a signal you need the new CPU sooner rather than later.
Yeah, I have seen games like Fortnite max out CPUs too. It really depends on how well the games are optimized. If you're unhappy with performance in some titles, it might be worth upgrading.

Exactly! Everyone looks at GPU utilization, but CPU can affect performance just as much. And hey, if you're getting solid FPS on a 1440p monitor, perhaps you don't need to rush into an upgrade.
