B550 and B650 chipsets strike a compelling balance, providing PCIe 4.0 support and robust features at a reasonable price point. High-end X570 and X670 options deliver maximum connectivity and overclocking headroom, but come at a premium. Based on our testing and analysis, for users prioritizing a blend of performance, features, and future-proofing without exceeding a mid-range budget, the MSI MAG B650M Mortar WIFI represents a particularly strong choice.
