Honestly, building on AM5 has been a bit of a trip. I spent weeks stressing over VRMs after a buddy of mine had a board throttle his chip during long sessions. Since you're pairing that with a 4080 Super, don't cheap out on the power delivery or you're gonna have a bad time when the system is under full load. Here is what I've learned the hard way:

• Watch out for board bios updates, some of the early ones were super unstable with memory training.
• Make sure the heatsinks on the VRMs actually have some mass to them, cause that chip can pull a surprising amount of power.
• Avoid boards that dont have internal headers for your case layout, it makes cable management a nightmare. Just be careful with the cheaper options out there, they aren't all built the same.
