I'm looking to upgrade my PC to an AM5 setup with a 7 9800X3D and a 5080 graphics card. However, I want to use the 5080 temporarily with a 5800X and 16 GB DDR4 RAM. My gaming will be at 1440p with a refresh rate of 165 Hz. I can't find a 5700X3D locally, so I'm curious about how the 5080 will perform with my current CPU and memory until I can fully upgrade.

The 5080 should perform fine with the 5800X. Just keep in mind that your PSU is really important here—make sure you've got enough power for everything, or you might run into issues.
As for specific games like Cyberpunk and Red Dead, the performance will vary. Expect the 5800X to limit the 5080 a bit, but nothing drastic—especially since your target is 1440p.
You might be leaving a bit of GPU performance on the table, maybe around 20-30%, due to the CPU hold-up. You could see some micro stutters here and there because of the memory, but it'll work fine until you're ready to fully upgrade.
It'll run okay; it really depends on the games you play. At 1440p, you might get some CPU bottleneck, but overall, it should handle most games pretty well for now.
