I'm planning a high-end AM5 build and really want to future-proof my storage and GPU lanes. I've been looking at X670E and B650E boards, but I'm confused about which ones offer true PCIe 5.0 support across both the primary M.2 and x16 slots without lane sharing. Which specific model handles this best for a stable, long-term setup?

If ur looking for the absolute best, you gotta go with an X670E board because it's built for exactly what you want!! Honestly, the ASRock X670E Taichi is a total beast for this - it handles Gen 5 on both the x16 slot and the main M.2 without any annoying lane sharing issues that some cheaper boards have. Another reallyyy solid pick is the ASUS ROG Crosshair X670E Hero if you want that premium feel... but it’s definitely pricier lol. Most B650E boards do Gen 5 too, but X670E gives you more breathing room for the long haul imo. I think the Taichi is the sweet spot? There design is top tier too. Anyway, for a stable setup that’s future-proofed, those two are basically the gold standard for high-end AM5 builds right now.

tbh I grabbed the ASUS ROG Strix X670E-E Gaming WiFi for my rig because I was sooo worried about future lanes... it's been totally rock solid since day one haha!!

Unfortunately, a lot of these AM5 boards arent as good as expected when you actually look at the block diagrams. I've been digging through manuals and its honestly kinda disappointing how many flagship models still force weird lane trade-offs. Not sure but IIRC, even some pricey X670E options will drop your primary x16 slot down to x8 the moment you plug in a second Gen 5 drive... which basically defeats the purpose of future-proofing. I think there are still some compatibility concerns with signal redrivers on the cheaper B650E boards too, which might lead to stability issues down the line if the trace lengths arent perfect. I dont have the exact list in front of me right now but someone told me the topology on some of these extreme boards is still way too crowded. Its a mess tbh. If you find a specific model you're eyeing, let me know and I can help you double-check the manual to make sure it doesnt have those hidden lane sharing traps... definitely want your setup to stay rock solid.
