Ans: NVIDIA SLI allows for up to two, three, or four GPUs to be linked together in a single SLI configuration, depending on the specific GPU model and the SLI bridge used. Following the same, you can go with a 2-way, 3-way, or 4-way SLI configuration in your system. It's worth noting that as technology evolved, NVIDIA has shifted its focus from traditional SLI to other technologies like NVLink and multi-GPU support through parallel processing. As a result, the availability and support for various SLI configurations may vary with future GPU releases.
