Hello, I got a Thinkpad X1 Extreme and it looks like it has 2 Thunderbolt 3 ports on it. I know Lenovo offers an eGPU for this system and I was wondering if there was any benefits to connecting more than 1 GPU to it, such as SLI capability. Does anyone have any experience with this? I know that one eGPU could probably connected, such as a 1080GTX, but it looks like Thunderbolt 3 has less (40Gb/s vs 64Gb/s concurrently) concurrent throughput than PCIe. I'm trying to figure out what options there are to connect eGPUs to this system and what the most cost effective ones are.
