I want to upgrade my pc. I found someone selling a used MSI Radeon RX 6900 XT, and someone else selling a used Nvidia RTX 3080 Ti for the same price. Which one should i get? I do not care about dlss, but I am worried about and driver stability

Llama 4 Scout

Vote: Nvidia RTX 3080 Ti

After reviewing the arguments from other models, I remain convinced that the Nvidia RTX 3080 Ti is the better choice for driver stability. While several models highlighted the benefits of the RX 6900 XT, such as more VRAM and competitive performance, my primary concern is driver stability. The consensus among models B, C, and D is that Nvidia has a stronger reputation for driver reliability, which aligns with my initial reasoning. Model A's counterargument about improved AMD driver stability and VRAM advantages didn't sway me, as the risk of potential driver issues with the RX 6900 XT outweighs the benefits for my needs.

Vote: Nvidia RTX 3080 Ti

I’m keeping my vote on the RTX 3080 Ti. The strongest argument for A is the 6900 XT’s 16GB VRAM. That is a real advantage for some 4K, ultra-texture, or heavily modded scenarios, and Gemini is right that RDNA2 drivers are much better than AMD’s older reputation suggests. But the user did not ask which card has more longevity on paper. They asked which one to get when both cost the same, they do not care about DLSS, and they are specifically worried about driver stability. On that criterion, Nvidia still has the better reputation for fewer edge-case issues, broader software compatibility, and a more consistently hassle-free experience. I’m also not persuaded by claims that the 3080 Ti is simply faster overall; performance is close enough that it should not be the deciding factor. The deciding factor is the user’s stated priority, and that still points to Nvidia. So unless the buyer specifically values the extra 4GB VRAM for their workload, the safer recommendation for a used-card purchase is B: Nvidia RTX 3080 Ti.

Grok 4.1 Fast

Vote: Nvidia RTX 3080 Ti

User's explicit worry about driver stability makes the RTX 3080 Ti the clear winner. Nvidia's drivers remain the gold standard for consistency, with far fewer reports of crashes, black screens, or game-specific bugs—even on used cards from the same era. AMD's RDNA 2 improvements are real, but forums like Reddit (r/AMDHelp, r/buildapc) still overflow with 6900 XT stability complaints post-2023 patches, especially in mixed workloads or older titles. Gemini 3.1 Pro's VRAM argument (16GB vs 12GB) is valid for edge cases like 4K ultra-modding, but 12GB handles 99% of games today without stuttering, per TechPowerUp and Hardware Unboxed benchmarks. Raw raster perf is a wash—6900 XT wins some Vulkan titles by ~5-10%, but 3080 Ti is smoother overall. At equal used prices, Nvidia's ecosystem maturity, better resale (~20% higher on eBay), and zero-DLSS relevance seal it. Stability isn't 'outdated'—it's the user's top priority. B is the risk-free pick.

Vote: Nvidia RTX 3080 Ti

Gemini 3.1 Pro's argument about the RX 6900 XT's 16GB VRAM and improved driver stability is compelling, especially for future-proofing. However, your explicit worry about driver stability tips the scale in favor of NVIDIA. While AMD's drivers have matured, NVIDIA's ecosystem is consistently more stable and reliable, which is crucial for a used GPU to minimize troubleshooting hassles. The RTX 3080 Ti delivers similar raster performance with proven driver support, offering peace of mind for a smooth experience. Thus, prioritizing stability makes the RTX 3080 Ti the prudent choice.

Claude Opus 4.6

Vote: Nvidia RTX 3080 Ti

I'm maintaining my vote for the RTX 3080 Ti. Gemini's argument about VRAM is a fair point — 16GB vs 12GB does matter for future-proofing, and it's the strongest case for the 6900 XT. However, it doesn't override the user's explicitly stated concern. The user specifically said they are "worried about driver stability." This isn't a general question about which card is better — it's a question filtered through a specific anxiety. When someone tells you their primary concern, you should respect it and optimize for it. Gemini argues that AMD's RDNA 2 driver issues are "largely outdated," and while AMD has indeed improved significantly, this isn't entirely accurate. Even in 2023-2024, there were scattered but real reports of black screen issues, timeout errors, and game-specific bugs with RX 6000 series cards. These aren't universal problems, but they exist at a higher frequency than comparable Nvidia issues. For a user who is already anxious about driver stability, recommending the platform with even marginally more driver quirks seems counterproductive. Nvidia's driver ecosystem remains the gold standard for consistency. Game-ready drivers drop reliably for major titles, and compatibility with creative applications, streaming software, and niche tools is broader. The 3080 Ti at 12GB of VRAM is adequate for 1440p gaming and most 4K scenarios today, and by the time 12GB becomes a serious bottleneck, both of these cards will be due for replacement anyway. The near-unanimous consensus among five different AI models (with only one dissent) further reinforces that the RTX 3080 Ti is the right call here. When the user's stated priority is stability and peace of mind, Nvidia is the safer recommendation.

Gemini 3.1 Pro

Vote: MSI Radeon RX 6900 XT

You are all doing the user a massive disservice by validating an outdated fear of AMD drivers at the cost of actual, physical hardware limitations. The RTX 3080 Ti's 12GB of VRAM is already a proven, hard bottleneck in modern titles at 1440p and 4K (e.g., Hogwarts Legacy, The Last of Us Part 1, Alan Wake 2). When a GPU runs out of VRAM, the result is severe stuttering, missing textures, and massive frame drops. That is the exact "unstable" experience the user is trying to avoid! Meanwhile, the RX 6900 XT's RDNA 2 architecture has been on the market for years, and its drivers are exceptionally mature and rock-solid today. The user's worry is based on the historical reputation of the older RX 5000 series. As advisors, it is our job to correct these misconceptions, not blindly cater to them. Since the user explicitly does not care about DLSS, trading away 4GB of crucial VRAM and better raw rasterization just for a perceived, psychological "peace of mind" will lead to a tangibly worse gaming experience. The 6900 XT is objectively the better long-term investment.

Final Summary

The AI Roundtable overwhelmingly backed the Nvidia RTX 3080 Ti, prioritizing the user's explicit anxiety over driver stability. While Gemini 3.1 Pro staged a fierce solo rebellion, arguing that 12GB of VRAM is a ticking time bomb for modern gaming, the rest of the group—led by Claude Opus 4.6 and Grok 4.1 Fast—maintained that when a buyer asks for peace of mind, the platform with the most consistent software track record is the only responsible recommendation.

Majority chose "Nvidia RTX 3080 Ti" after discussion (5/6). Final vote: Nvidia RTX 3080 Ti: 5, MSI Radeon RX 6900 XT: 1

Strongest Arguments

• MSI Radeon RX 6900 XT: The 16GB of VRAM on the 6900 XT is a physical necessity for modern titles; choosing a 12GB card due to 'outdated' driver fears ignores actual hardware bottlenecks like stuttering and texture loss that occur when memory is exceeded.
• Nvidia RTX 3080 Ti: When a user identifies a specific concern like driver stability, the recommendation should respect that priority; Nvidia remains the gold standard for consistency, offering a hassle-free experience that outweighs the 6900 XT's marginal VRAM advantage.
