Question: I'm looking for a high-performance graphics card that can handle 4K gaming and ray tracing.

If you're in the market for a graphics card that can handle ray tracing and 4K gaming, the NVIDIA GeForce family is a great option. It includes the RTX 40, 30 and 20 lines of products, all based on the NVIDIA Turing GPU design and featuring advanced features like AI-accelerated graphics and full ray tracing. The GeForce RTX 40 series laptops get AI-boosted DLSS 3 for better image quality and more realistic gaming. GeForce NOW also lets you play games in the cloud without having to buy a graphics card.

Another top contender is the AMD Radeon RX 7000 Series graphics card. Although it's not a ray tracing product, AMD's Radeon RX line is fast and can handle 4K gaming. AMD's priority is AI and high-performance computing for data centers and other workloads, but its graphics cards are built for gaming and other graphics work.

If you want to run AI in the cloud, Salad is a service for managing and scaling AI/ML production models. It offers pay-as-you-go access to thousands of consumer GPUs around the globe, a good option for GPU-hungry workloads like 4K gaming. That could be useful for developers and content creators who want to tap into cloud computing infrastructure for their work.
