Is the RTX 4090 worth it over the RTX 4080?

For 4K gaming, ray tracing and AI work, yes: it is clearly faster and has more memory. The 4080 makes more sense if you play at 1440p or want a smaller, cooler card.

Will it fit in my case?

Check clearance first. Partner boards like the ROG Strix are about 14 inches long and take three or more slots, so many mid-tower cases will not fit them.

What power supply does it need?

Plan on a high-wattage PSU with the right 12VHPWR connector or adapter. NVIDIA and partners recommend a strong unit for the whole system, not just the card.

Is 24 GB of memory useful for gaming?

At 4K with high textures it helps, but the bigger benefit is for AI models, 3D rendering and video work that need large memory buffers.

Does it support DLSS and ray tracing?

Yes. It supports DLSS up to frame generation and hardware ray tracing, which are its main advantages over older generations.

Retail cards typically include the graphics card, a power adapter cable and a support bracket on larger models. Check the specific partner model for details.
