ASUS ROG STRIX B650E-F is solid if you want PCIe 5.0. Excellent power delivery, good BIOS, and the price is reasonable compared to X670. Just make sure you update the BIOS before installing the CPU.

For the 7800X3D, I’d recommend an AM5 motherboard with solid VRMs and PCIe 5.0 support. The ASUS ROG Strix X670E-F or MSI MAG X670E Tomahawk are great options, offering excellent performance and future-proofing. If you’re on a budget, the B650 chipset like the Gigabyte B650 AORUS Elite AX still delivers great value without compromising much on features.

Any b850 or b650 cards are recommended.
