It's honestly disappointing how many premium cases still don't address this properly. I've spent way too much time testing different solutions and unfortunately, most of the horizontal arm brackets are basically useless. They usually rely on the flimsy metal between the PCIe slots for leverage, which eventually just bends under the weight of a 3080 anyway. It's a fundamental design flaw that we even need these. In my experience, you need something that anchors to more stable points. I've moved away from those magnetic pillars because they tend to shift if you ever move the tower or even just bump the desk. Here are the options I actually find reliable:

• Lian Li GB-001 Anti-Sag Bracket
• This is probably the cleanest technical solution available. It mounts directly to the motherboard standoffs, so the support is coming from the rigid frame of the case itself.
• ASUS ROG Herculx Graphics Card Holder
• This is a massive upgrade if you have the clearance. It features a solid ratcheting height adjustment and even an integrated spirit level to ensure the card is perfectly flat. The technical reality is that you need to be careful where you apply pressure. Never support the card by the fans... always aim for the edge of the shroud or the backplate. It's a bit of a headache to set up perfectly, but it's better than watching your PCIe slot slowly die.

I've been building rigs for years and sag is definitely worse with these modern cards. In my experience, simple pillars are the way to go. I swear by the Cooler Master Universal Graphics Card Holder V2 Tempered Glass for a clean look. If you want something more low-key, the Antec GPU Support Bracket Aluminum Alloy is cheap and keeps things level without any fuss. Don't overthink it.

No way, I literally just dealt with this yesterday. Small world.
