I often find myself surprised when people state that they're not moving on to the next generation platform, because their current system, at the final stage of the previous platform, is doing great.
Maybe I'm weird, but I really don't think that AM5's rather audience is people on the 5000 series chips of AM4.
Hell, even recently, a friend looking for a new setup and looking at the 7800X3D, but who's on a budget restriction, I steered in the direction of going with a 5700X3D based system, as that'll give them more money to spend on the GPU. And really, do they need the absolute king of the hill gaming CPU? No, they can do just fine with the CPU that beats MOST others in gaming, they don't need the best of the best.
