What makes the RTX 4090 special?
The NVIDIA GeForce RTX 4090, released in October 2022, remains a benchmark among graphics cards in 2025 thanks to its Ada Lovelace architecture. In my opinion, the RTX 4090 is a card that is still very relevant and important, but if you only use it for gaming, it can be considered overkill, that is, excessive for that purpose.Its power is undeniable: it allows play in 4K fluently and tackle tasks such as AI training either 3D rendering, which increases its appeal, but also makes it expensive and difficult to access. This RTX 4090 card debuted at $1599 USD, establishing itself as a premium option for those seeking the best in performance.
In this review, we'll explore the RTX 4090 graphics card's features, performance, and requirements to get the most out of it, including RTX 4090 power supplies and cases.

Conclusion: The RTX 4090 in the spotlight
The GeForce RTX 4090 remains a elite graphics card, launched at $1599 USD, and in 2025 maintains its place as the best available. Personally, I think it's too powerful if it's only for gaming, where an RTX 4080 Super would cover your needs with a notable saving.. However, for AI, 8K design, or 3D rendering, this RTX 4090 graphics card is unbeatable, even surpassing the RX 7900 XTX. Its size, consumption, and heat demand spacious RTX 4090 cases and powerful PSUs, which implies a large investment in components. If you're looking for the best, this GPU remains a prime target.
