I finished my current computer earlier this year and running a Corsair MP600 which is close to 5GB/s. I have no plan to upgrade at the moment but if at anytime I find it has become a bottleneck for me that could change. At this point I think it unlikely it something that will require upgrading for me till at least 2023.
Did not vote in poll because both Gen 4 options says planning on upgrading. I guessing the second to last option was intended to say Not Planning to Upgrade but I wait till it changed before voting.
