Tri-SLI only offers a improvement over SLI at high-res

SLI, which stands for Scalable Link Interface, allows you to connect two or more graphics cards in parallel to increase performance. This technology is available on most modern NVIDIA graphics cards and allows you to use two or more graphics cards to work together to deliver a significant performance boost. Tri-SLI, on the other hand, is a specific type of SLI that uses three graphics cards working together to deliver even more performance.
Is it Worth the Investment for High-Res Gaming?
When it comes to building a high-performance gaming PC, one of the most important components to consider is the graphics card. A single high-end graphics card can provide great performance, but for the ultimate gaming experience, many enthusiasts turn to multi-GPU configurations, such as SLI (Scalable Link Interface) or Tri-SLI (3-way SLI). However, the question remains, is Tri-SLI worth the investment for high-res gaming?
Although Nvidia is still supposedly “working hard” to enhance the drivers, the benchmarks we’ve already seen regarding three-way SLI show it to be a disappointment, and VR-Zone’s tests are no exception. Using three 8800 Ultra’s on a nForce 790i SLI reference board, VR-Zone witnessed a 26% improvement in 3DMark06 at 1920×1440 with 16x AA Quality and 16x AF. However, when using no AA/AF, there is only a 5.6% performance boost over two-way setups.
Using the Forceware 167.10 3-way SLI beta drivers on Windows Vista, we need to tune up the AA/AF to actually see the performance differences between 2-way and 3-way SLI. We got a 26% improvement in 3DMark06 at 1920×1440 resolution, 8 sample AA with 16x AA Quality and 16x AF over 2-way SLI. Without AA/AF, we got only a 5.6% performance boost. Nvidia is still working hard to enhance the 3-way SLI drivers further so we hope to see a bigger FPS boost in latest games which are more GPU intensive with better multi-GPU support. So make sure you run those intensive games to high resolutions like 1920×1440 or 2560×1600 etc with all the image quality settings to the max to enjoy full benefits of a 3-way SLI setup.
Conclusion
Tri-SLI is a great option for gamers who are looking to run games at high resolutions with the highest possible settings. It provides a significant performance boost at high resolutions, such as 4K or 5K, and allows you to run games at a higher frame rate and with better image quality.
However, it’s important to note that Tri-SLI is not a universal solution for gaming and the improvement in performance is only noticeable at high resolutions. Additionally, because Tri-SLI requires three graphics cards, it’s also a much more expensive option than single or dual-card SLI, so it’s important to weigh the cost-benefit before making a decision.
