I am dealing with this exact same issue right now and honestly its been a nightmare trying to decide for the last few weeks. Every time I think I finally found the right card, I read something that makes me think the reliability is just not as good as expected for this generation. Some stuff that has me worried:

• Potential for cable melting issues on the ASUS Dual GeForce RTX 4070 SUPER
• Random black screens people keep reporting on the Sapphire Pulse AMD Radeon RX 7800 XT
• Fan noise and bearing issues on the cheaper dual-fan models Unfortunately it feels like there is no perfect answer here and I am just as stuck as you are. Just curious tho, what kind of power supply are you planning to use for this build? I am wondering if some of these reliability issues are just bad PSUs or if the cards themselves are just flaky...

Noted!

It is kinda disappointing that we are still dealing with these VRAM limitations at the 500 to 600 dollar price point. Honestly, neither card feels like the massive jump we were all hoping for. I have been looking at the bandwidth specs and the 192-bit bus on the 4070 Super is unfortunately not as good as expected for high-refresh 1440p. It is frustrating that you have to choose between better software or just having enough raw memory for future games.

• MSI Gaming X Slim GeForce RTX 4070 SUPER 12GB
• ASRock Phantom Gaming AMD Radeon RX 7800 XT 16GB OC I had a moment to think about the data and I hate that we have to pick between better frame gen or actually having enough headroom for textures in two years. If you are really watching the budget, I would just grab the 7800 XT when it is on sale for closer to 480. Paying over 600 for a 12GB card just feels wrong tho when you want it to last...

Honestly, I get the hesitation. I switched over to the 4070 Super a few months back after using AMD for years, and while the software features like frame gen are cool, dont just look at the marketing sheets. If you go Nvidia, please for the love of god make sure your 12VHPWR cable is seated all the way in. I spent way too much time obsessing over that connector when I first built my rig. My experience? The card is super efficient and runs cool, which was a nice change of pace. I havent had those black screen issues people talk about, but I stay away from aggressive overclocks now. Just set it and forget it. If youre chasing raw VRAM for longevity, the 7800 XT route is tempting, but for pure 1440p stability, I havent really had any reason to complain about my current setup. Just watch your power cables and dont overthink the benchmarks too much, they all perform well enough in real games.

I think most people will choose RTX 4070 SUPER.

When comparing the RTX 4070 SUPER and the RX 7800 XT for gaming in 2024, several factors come into play such as performance, features, ray tracing capabilities, and price.

The RTX 4070 SUPER, based on NVIDIA's latest architecture, offers excellent performance and efficiency. With its superior ray tracing capabilities and support for DLSS (Deep Learning Super Sampling), it provides smoother gameplay at higher resolutions. DLSS, in particular, is a game-changer, as it leverages AI to upscale images, allowing for higher frame rates without a significant loss in image quality.

On the other hand, the RX 7800 XT, powered by AMD’s cutting-edge RDNA 3.0 architecture, is known for its strong rasterization performance and competitive pricing. This GPU excels in raw performance metrics, often matching or exceeding the RTX 4070 SUPER in games that do not heavily rely on ray tracing. AMD's FidelityFX Super Resolution (FSR) also offers a means to improve frame rates, although it generally does not match the quality level of DLSS.

In conclusion, if you prioritize ray tracing and AI-driven enhancements, the RTX 4070 SUPER is likely the better choice. However, if rasterization performance and value for money are your primary concerns, the RX 7800 XT could be more appealing. Ultimately, the best choice depends on your specific gaming preferences and budget.
