    No not for the GPU.

    Nope not for graphics but benefits in pcie 4 for NVME 4.0 drives only and lets be honest even version 3 are fast enough for now and most people can't tell the difference from a sata ssd to a NVME ssd.

    Not for the 3080 really , biggest advantage of pcie 4.0 is for SSD speeds.

    Not for games there isn't.

    Loading times on games between pcie 3/4 nvme drives are basically nil. Even the difference between an nvme and sata SSD, basically nil, even though on paper one is technically 10 times faster.

    There are some, non gaming uses that may see a bit of a difference with transfer rates.

    This may change over time, but certainly the case as of today.

    Definitely no difference for a GPU.

    Even for an SSD, it depends what you're using it for. Sustained, large transfers will be better under the new pcie 4.0 drives.

    But if you're comparing game loading times, the fastest SSD still happen to be PCIE 3.0 drives (not because of PCIE 3.0, of course). The Intel Optane 905P will dominate any game loading benchmark and even the SK Hynix P31 tends to outperform the 980Pro in level loading.
