> Those Gen3 x1 slots are limited to 7.88Gbps so they are pretty pointless This reviewer tested the M.2 capture card with two 1080p60 signals that have a data rate of 3.2Gbps each, so a PCIe gen3 x1 slot would have been plenty of bandwidth for this use case (but not for capturing at 4k). Don't make the mistake of believing that a device which has lots of PCIe lanes actually needs all of them active to fulfill its purpose and be useful.
