Ok thanks, that puts my mind at ease. But why does it not matter? Isn't GPU mining a really computationally intensive process? Is it just that Gen3 lines are advanced enough that they can handle any throughput that GPU/CPU pathway requires?

Hi all,

I'm pretty new to mining. I was thinking of setting up a hybrid mining/workstation using two GTX 1060 GPUs. Most of the motherboards I'm looking at (like this one: https://www.msi.com/Motherboard/X370-GAMING-PLUS/Specification) feature two full-sized x16 PCIe connections, but the motherboard specs say that they function as either x16 (if using one GPU) or x8/x8 (if using two GPUs). Does not being able to run them at x16/x16 matter for hash rates? If not then could I potentially use another Gen2 slot for another GPU (even though it's an x4)?

Let me know if this makes any sense.
