My father and I built this PC about five years ago, and it's starting to struggle with newer AAA games. At 2560×1440 and 144 Hz, I'd like to play at high or very high settings—or at least maintain solid performance at medium settings. My budget is around $2,000 USD, and I'm unsure whether to upgrade individual components or replace the whole system. The current build is an Intel Core i7-10700K, GeForce RTX 3070 8GB, MSI MPG Z490 Gaming Edge WiFi motherboard, 32GB of DDR4 memory, Seasonic Focus GX 850W power supply, and a 2TB Western Digital Blue SATA SSD. I also need to replace the case fans. What should I prioritize, and is $2,000 enough for a worthwhile upgrade?

You can probably reuse the case, power supply, storage, and memory for now. Upgrade the GPU first, then check whether performance is limited by the CPU in the games you play. If it is, replace the CPU and motherboard later. A newer platform would ideally use DDR5, so a full CPU-and-motherboard upgrade can become expensive, but your $2,000 budget should cover a strong GPU and leave room for a future platform upgrade.
There’s no urgent need to replace the entire computer. The 10700K is dated, but it isn’t automatically too slow for 1440p, where the GPU usually matters more. Put most of the budget toward the graphics card, add good-quality case fans, and keep the rest of the system unless monitoring shows the CPU regularly maxing out or causing frame-time issues.
If you would rather build something that will last several years without another major upgrade, wait until the next major CPU platforms are available and save a little more. A new CPU, motherboard, DDR5 memory, and GPU would provide a cleaner long-term setup, but current components and storage prices can make that less cost-effective than upgrading the graphics card now.
Start with the graphics card. At 1440p, the RTX 3070’s 8GB of VRAM is likely the biggest limitation in newer games. A Radeon RX 9070 XT with 16GB or a GeForce RTX 5070 Ti would be a substantial improvement, and your 850W power supply should be suitable. The i7-10700K is older, but it can still handle 1440p gaming reasonably well, so you may not need a complete rebuild immediately.
