But this is a product where I might get personally but won't recommend.
I too, have a hard time recommending ARC for most gamers. Older games are hit or miss on both A and B series. CPU heavy games are tough if you don't have a CPU with enough grunt. No streaming, recording, or metrics overlay built in. Frame pacing issues in games where the other vendors are flatlines. Sketchy long term support prospects. Can lose significant performance in PCIe 3 mode in some titles.
ARC is best for those of us that have a better gaming card already, want to support player 3, and enjoy the box of chocolates experience.
Here is B570 build that also gets close but no cigar. Mistakes on parts choices and testing methodology. Should have went with the Phantom Spirit and looked for a used Z series so they could overclock the 12600kf. At 4.9-5GHz it would have made a difference. 16GB DDR4 is a crime with how cheap DDR4 is. No excuse for not going 32GB, it's 2025.
Left RT on for Rivals instead of competitive settings, come on man. That's the shilly bros for you. Spiderman 2 they didn't even bother getting to free play with crowds and traffic. Frustrating, because I think a fairly standard overclock on the 12600kf would show itself to be a great choice for the build.
