I'm considering replacing my Palit RTX 3080 GameRock 10GB with a Radeon RX 9070, possibly the Sapphire Nitro+ model. I mainly play at 1440p and have checked that there shouldn't be a serious CPU bottleneck, but I'm not very experienced with hardware and would appreciate a second opinion.
My current system has an Intel Core i9-10900KF, 32GB of Patriot Viper Steel DDR4-3200, and an MSI Z490-A PRO motherboard. A friend suggested selling the entire PC and building a new one, but I'm concerned that would cost much more than I can comfortably spend right now. Would a GPU-only upgrade make sense, or is it worth replacing the whole system?

Your current PC is still well balanced, and the 10900KF remains a capable gaming CPU. For 1440p, upgrading only the graphics card makes the most sense if you actually need more performance. A regular RX 9070 should work well, and you probably don’t need to pay a huge premium for a heavily overbuilt model like the Nitro+.
CPU bottlenecks depend heavily on the game, resolution, and target frame rate. At 1440p, the 10900KF should be fine with a 9070 or 9070 XT in most games, although CPU-heavy titles or very high-refresh gaming may show some limitation. I’d keep the current platform and upgrade the CPU, motherboard, and memory later when the performance gain is clearly worth the cost.
I wouldn’t replace the entire PC unless you specifically need higher minimum FPS, newer platform features, or substantially better productivity performance. A complete upgrade would mean buying a CPU, motherboard, DDR5 memory, graphics card, and possibly a power supply, which is a lot to spend for a relatively modest gaming improvement. Set a budget first, then compare the GPU’s cost after selling the 3080.
Check the actual price difference before buying. The RX 9070 is faster than the RTX 3080, but the improvement may not justify a very expensive upgrade, especially if you’re already happy with your frame rates. Selling the whole system would be a much bigger expense and isn’t necessary just because newer platforms exist.
You could also get a little more life out of the current build by tuning or overclocking it, assuming your cooling and power supply are suitable. The 3080 is still a strong 1440p card, so saving your money and upgrading later is completely reasonable. If your games already run smoothly at the settings you want, there’s no urgent reason to change anything.
The 10900KF is roughly in the range of older Ryzen 5000 gaming chips, so it isn’t cutting-edge, but that doesn’t mean it will seriously hold back a modern GPU in every game. It’s better to check your own frame rates and GPU usage than assume a bottleneck from the parts list alone.
