It would function perfectly fine. Ensure the 9900K operates at 5GHz across all cores. From what I understand, most units can handle this with adequate cooling. Although my setup uses an older 5820K in overclocked mode, it performs well with a GTX 1080Ti. It may not be the top performer anymore, but it remains one of the fastest available near the RTX 2080 lineup. I don’t see any issue letting it match the RTX 3080 when it launches. It also provides enough cores to handle modern, multicore games. The 10th generation isn’t a huge leap unless you look at stock performance with better Turbo algorithms. When you push it manually, that difference fades and it still keeps up without major trouble. Since you likely already own the 9900K, you’ll also save money.
Stick with Intel alone? Not so much. AMD delivers solid performance at a fraction of the cost. When you look beyond gaming, its strengths shine in various areas. The 4000 series also outperforms Intel’s cutting-edge nodes.
Upgrading to a 9900k wastes resources unless you require the raw core count for parallel processing. Those limited frames you gain become pointless when you must replace an entire platform worth around 1000€ just to achieve that. Better allocate those funds toward another graphics card upgrade after the RTX 3000 series, or save them for a bigger platform upgrade in the future. This 9900k will serve you well until AMD introduces the AM5 platform, and if conditions are right, Intel might release a new CPU then. Until then, try maximizing the clock speed of this chip—you're good to go.
I own two RTX 2080 Ti graphics cards—one EVGA XC and one FTW3 Ultra. The latter supports higher clock speeds, which can cause bottlenecks at 1440p resolution, whereas the XC handles it better. To compare their performance, I use specialized software like FireStrike or TimeSpy. Performance peaks around 2040 MHz, matching the threshold where 4K at 3840x1600 becomes challenging. At 5K resolution and higher, it shouldn’t impact me, but this trend could become relevant soon. Previously, my GTX 1080 Ti was sufficient, but now the RTX 2080 Ti demands more power. The 10th generation architecture is similar to the 9th, though with more cores; gaming performance isn’t significantly affected. Overclocking at 5GHz didn’t yield major gains in my tests, though a 5.3MHz might help. I’m leaning toward a 10th-gen CPU but fear a disappointment risk over 50%. The upgrade mainly benefits modded titles that use fewer cores. I had to drop all-core 5GHz overclocks from my CPUs, including the i9 9900K, after the latest Windows update caused crashes in games using Havok physics. I’m hoping this issue is temporary, but I’ve removed similar overclocks before for comparable problems.
