I bought a prebuilt PC a few years ago and want to upgrade it gradually, but I'm not very familiar with PC hardware. My current system has a Ryzen 5 5500, Deepcool AK400 cooler, Gigabyte B550M DS3H motherboard, 16GB of DDR4-3200 memory, a 1TB Crucial P3 NVMe SSD, an RTX 3060 12GB, a Deepcool PK650D 650W Bronze power supply, and a Deepcool MACUBE 110 case. I recently got an ASUS ROG Strix OLED XG27UCDMG 4K 240Hz monitor and mainly use the computer for gaming. What should I upgrade first to make the most of the display, and which upgrades would not be worthwhile? I'm fine with improving the system one part at a time.

At 4K, the graphics card is going to be the biggest limitation by far. An RTX 3060 can play many games at 4K with reduced settings or upscaling, but it won’t come close to 240 FPS in modern titles. Start with the GPU if your budget allows, then consider a stronger power supply if the new card requires more wattage or a newer power connector. A 16GB card would also give you more breathing room for newer games.
The case, cooler, SSD, and possibly the memory are reasonable parts to reuse. I wouldn’t replace the motherboard unless you move to a new platform, and I wouldn’t upgrade from 16GB to 32GB until you start seeing memory usage or stuttering in the games you play. Check the exact GPU power requirements before buying, since the 650W Bronze supply may be fine for a moderate upgrade but may not be suitable for a high-end card.
If you want a cheaper upgrade while keeping the current motherboard and DDR4 memory, look for a Ryzen 7 5700X3D, assuming it’s supported by your BIOS. It can noticeably improve minimum FPS and help with high-refresh-rate gaming, although at 4K the GPU will usually matter more. The AK400 should be adequate for that processor, and your existing RAM can be kept for now.
Don’t feel obligated to build a system capable of driving 4K at 240Hz. That monitor is excellent, but reaching 240 FPS at 4K in demanding games requires an extremely expensive GPU and often substantial compromises. You can still enjoy it at 4K with settings adjustments, upscaling, and frame generation, or use a lower resolution when you want higher frame rates. Set a total budget first before choosing parts.
A platform change would mean buying a new motherboard and DDR5 memory as well, so staying on AM4 with a 5700X3D is the more economical CPU route. A full new build only makes sense if you’re also targeting a high-end GPU.
