I have about $500 to spend on a gaming PC and want something that can handle most games at 1080p with sensible settings. Most parts will be used or purchased locally. My current list is a GTX 1080 Ti for $120, Ryzen 5 5600 for $112, an inexpensive air cooler for $12, a Soyo B450M AM4 motherboard for $54, 16GB of 3200MHz RAM for $50, a 512GB NVMe SSD for $50, a 500–650W power supply for $40, and a case with fans for $40, totaling roughly $478. Are these parts compatible, and are there better-value choices or potential bottlenecks I should watch out for?

If you can get an RX 6600 for only about $40 more, it is worth seriously considering. It uses much less power and is newer, while offering similar or better performance in many games. The 1080 Ti still has strong raw performance and more memory, though, so keep it if the card is tested and the seller is trustworthy. For either GPU, inspect temperatures and test for crashes or artifacting before committing.
You could use the Ryzen 5 5600's stock cooler if you can find one, then put the cooler money toward a better motherboard or power supply. A decent B550 board would offer newer connectivity and usually better BIOS support, but it is not essential for gaming performance if the B450 board is known to support the 5600. Check the exact board model and seller reputation carefully, especially with inexpensive imported hardware.
The processor is used and does not include a cooler, and B550 boards cost about $40 more where I live. I may stick with B450 if I can verify the BIOS and reliability.
This should run far more than older games. A Ryzen 5 3600 and RX 580 can already handle many newer titles at playable settings, so this combination should do well at 1080p if you adjust demanding settings. You may need to lower textures or other options in the newest games, and the 512GB SSD will fill quickly, but there is no obvious CPU bottleneck for this budget.
The build is generally well balanced for 1080p. The 5600 pairs nicely with a 1080 Ti, and 16GB of dual-channel RAM is still adequate. The biggest concern is the power supply: avoid an unknown 500W unit, because the 1080 Ti can draw a lot of power. A reputable 600–650W model would be a safer choice. Also confirm that the B450 board has a BIOS version supporting Ryzen 5000 before buying.

The RX 6600 is available locally for roughly $40 more, so I am comparing its lower power use and newer support against the 1080 Ti's stronger performance and larger VRAM capacity.
