I'm planning to build or buy a gaming PC in the USA for around $1,500, possibly using the money I receive for my 18th birthday. I've been using a GTX 1080 Ti for about four years and am ready for a major upgrade. The games I play most are Rust, Rainbow Six Siege, Overwatch 2, Apex Legends, Arma, Dota, and Valorant. I'd like to reach roughly 140–250 FPS at 1080p in Rust if possible, and I know that game benefits heavily from strong CPU performance. I've heard the Ryzen 7 7800X3D and 9800X3D recommended, but I'm not sure whether either fits this budget. I already have all my peripherals, but I still need a case and every other internal component. I don't care much about appearance. I may also sell my current PC to a friend for about $400, which would give me more flexibility, although that money is separate from the initial $1,500 target. The nearest major computer parts store is about an hour and a half away.

Prices have made a 7800X3D build much harder to fit into this budget. A strong CPU, motherboard, and 32GB of RAM can approach $1,000 by themselves, and a GPU that is clearly faster than a 1080 Ti may cost another $500. With the case, cooler, PSU, and storage added, a sensible $1,500 build will probably need a 7600X3D or 7500X3D, a 1TB SSD, and carefully chosen midrange parts. Store bundles are usually the best way to save, while online combo deals can help if the nearest store is too far away. Avoid using only one stick of RAM; dual-channel memory is important for gaming performance.
A 7800X3D or 9800X3D build will be difficult at $1,500 once you include DDR5 memory, storage, a graphics card, power supply, case, and cooler. A Ryzen 5 7600X3D or 7500X3D would be a more realistic choice and should still deliver excellent gaming performance. You could also keep the 1080 Ti temporarily and spend more on the platform, or look at a midrange GPU such as an Arc B580 to keep the total under control.
The budget is tight for a high-end AM5 system. A rough allocation would be about $70 for the case, $100 for the motherboard, $100 for the power supply, and $40–70 for CPU cooling. That leaves much less for the processor, 32GB of DDR5, a 1TB SSD, and a graphics card. A 7800X3D alone can cost around $350, while 32GB of DDR5 and a faster-than-1080-Ti GPU take up a lot more of the budget. At 1080p, a Radeon 7700 XT-class card should provide high frame rates, but you may need to choose a less expensive CPU such as the 7600X3D or consider an older AM4 platform to put more money toward the GPU.
The current PC was built about three years ago and has a newer motherboard, CPU, and power supply. My friend is interested in buying the complete working system for around $400, not just the graphics card, so I’m comfortable using that sale to help fund the upgrade.
Try putting the complete parts list together in a compatibility tool before buying anything. Check that the graphics card outputs match your monitor, and consider a tray CPU if it is meaningfully cheaper—the processor is the same, but it may not include retail packaging or a boxed cooler. Bundle discounts can make a big difference, especially for the CPU, motherboard, and RAM.

The closest parts store is about an hour and a half away, so I probably won’t be making frequent trips there, but I’ll check whether a bundle deal would make the drive worthwhile.
