When I first got my RTX 4090 in 2022, I a**umed that my 12-core Ryzen 9 5900X would still be more than enough for gaming. After all, this CPU wasn’t even two years old when the 4090 launched. So I saw no reason to rush and get an 8-core CPU like the 5800X3D just because it’s faster. And for the first year or so, the a**umption felt correct. I was primarily gaming on my 4K/160Hz monitor, while occasionally switching to my 1440p ultrawide OLED to enjoy open-world AAA t**les.
