Have you considered upgrading your CPU?
He should play with the 12700k since it offers more extra 2 cores. For video editing and streaming, 13600k could be slightly better.
You'll mostly rely on it for gaming, though you could use it for light tasks later. The 13600k would still offer better performance than the 12700k.
I might not receive the 14600kf because I don’t wish to exceed my budget.
I also acquired a 500-watt power supply. It should function, though with limited performance. I still need to swap it out.
