The best argument for grabbing a 5080 right now, if you can find one at $999 in the first place, is that the only cards that come close to its performance are either way more expensive than they're supposed to be (the 4080 Super) or not cheap enough to justify the Nvidia-specific features you give up (AMD's Radeon 7900 XTX).

The Nvidia RTX 5090 is easily the best graphics card on the market right now, offering fantastic performance for gaming, creating, and AI workloads that few other cards can compete with. There is one card that can hold its own against Nvidia's latest high-end card, and that's Nvidia's last-gen flagship, the Nvidia GeForce RTX 4090.
