If you want 280hz then you’re gonna need a beefy CPU. But if you want to go with something more sane like 144hz then you could drop to a regular 7700x and be good.

I’m personally morally against CPU bottlenecks (they pain my soul) so I’d personally spend the extra money on it. But not everyone is as bothered by them as me.

You could drop down to a ryzen 5 cpu and a 140hz monitor if you want to save a bit.
