RTX 3090 SLI - We Tried so Hard to Love It

The video RTX 3090 SLI - We Tried so Hard to Love It investigates whether the RTX 3090 can still enable meaningful multi-GPU gaming through NVLink despite NVIDIA halting official SLI development. The host starts by outlining the fading relevance of SLI and contrasting it with the RTX 3090’s NVLink connector, introducing the central question: can two 3090s work together for gaming, and does it deliver a tangible benefit on current titles and APIs? He details the hardware choices, including an Asus ROG Strix RTX 3090, an MSI Z490 GODLIKE motherboard, and the power and cooling challenges of a dual-3090 setup, emphasizing the unusual but real-world constraints like limited availability of cards and the need for headroom in power delivery. The segment also covers how NVLink is positioned as a faster interconnect primarily intended for data center and AI workloads, before being repurposed for gaming with the 30-series cards, setting up the experimental framework for testing SLI with a heavy emphasis on real-world gameplay rather than synthetic benchmarks. The initial boot and configuration phase reveals both the excitement of stacking two GPUs and the practical hurdles, including power delivery considerations and airflow design inside a case, which becomes a running theme throughout the testing. The crew surveys a catalog of SLI-capable games and prepares to push Shadow of the Tomb Raider and other titles to the limit, with a focus on 4K maxed-out visuals and motion blur, to see if the experience justifies the complexity. The early results frame a skeptical conclusion: despite high GPU usage and impressive theoretical bandwidth, SLI does not deliver a consistent, noticeable uplift in frame times or gameplay smoothness, reinforcing the idea that SLI has become obsolete for most consumers. The video pivots to a candid assessment of power draw and thermal performance, underscoring spikes that can tax even large-capacity PSUs, and ends with a tempered recommendation to rely on single-GPU setups for most users while acknowledging the unique, extreme case experience that dual RTX 3090s offer for enthusiasts. The verdict is pragmatic and grounded in observed data: SLI on the RTX 3090 is largely a niche curiosity that failed to translate into broad gaming benefits, paired with a vivid demonstration of heat, noise, and power challenges that accompany such an overkill build.
