For what you’re spending on this, I would highly recommend throwing in a 1440p monitor. The difference from 1080p is night and day. The 7900XT will have zero issues with it, and you can find a solid 27" one for cheap nowadays so long as you’re not trying to find an OLED or something with a stupid high refresh rate.
That’s about the only feedback I have here though, the rest of this build looks good!
The last time the US fought China it amounted to that as well. And that was back when the PRC was a bombed out rural husk with little to no industry.
