Are they compatible with B450 and X470 boards?

Yes, with a BIOS update. 400 series boards (B450, X470) support Ryzen 5000, but some makers may require installing a Ryzen 3000 first to flash the BIOS or using an update kit. Check support on your board maker's site before buying.

Is it worth upgrading from Ryzen 3000 to one of these?

With a Ryzen 5 3600 or better at 1080p on a mid-range GPU, the jump will be moderate. From a Ryzen 5 2600 or lower, or at 1440p with a powerful GPU, the improvement is noticeable, especially with the 5800X3D.

What cooling does the Ryzen 7 5800X3D need?

At 105 W TDP, the 5800X3D runs best with a quality tower cooler or a 240 mm AIO. The 5600 and 5700X are fine with stock coolers or a decent 90-120 mm heatsink.

Can they bottleneck an RTX 4080 or RX 7900 XT?

In most games at 1440p or 4K, the GPU will limit performance before these CPUs do. At 1080p in very demanding titles, the 5800X3D gets closer to modern Ryzen 7000 chips thanks to its 3D cache.
