I've been using this system since 2019 and it has treated me well, but I'm starting to consider a graphics card upgrade. The current build has an i9-9900K, an RTX 2080 Super, and 64GB of DDR4 memory. I mainly play at 1440p, though I'd like the option to stretch to 4K. What GPU would be a sensible upgrade without the processor holding it back too much?

A Radeon 9070 XT would be a strong match for this system and should provide a noticeable jump over the 2080 Super. It would be especially worthwhile if your priority is 1440p with high settings or occasional 4K gaming.
Don’t worry too much about finding a GPU that has absolutely zero bottleneck. Even a 4090-class card can benefit an i9-9900K in the right games and settings. At 4K, the processor is generally less limiting, while at high-refresh 1440p you’re more likely to run into a CPU limit.
Your target FPS matters just as much as resolution. For example, a newer high-end GPU can run into the 9900K’s limits in busy multiplayer scenes at 1440p, particularly if you’re trying to stay above 100 FPS. If you’re happy with more moderate frame rates or play at 4K, you can choose a considerably stronger card without the CPU being a major problem.
The right choice depends heavily on the games you play, your target frame rate, and whether you’re aiming for 1440p or 4K. A high-end card can still be useful with this CPU, especially at 4K, where the GPU does more of the work. A card around the RTX 3080 Ti class would be a reasonable balance, but newer equivalents could also make sense depending on pricing.
