    Honestly those were the only interesting things to see with PCI-E 4.0...

    I'm still running a pair of R9-290xs on a Z97 board with a i7-4790k CPU. The GPUs are in XFire @ x8 each. For the primary GPU I get a score of 6.36GB/s. Does that seem right for PCIE 3.0?

    The max theoretical speed of 8x PCIe 3.0 is 7.88 GB/s.
    With a bit of overhead for the real world numbers i'm guessing 6.36 is around the real value or close to it.

    On my B450m board with a single card 16x PCIe 3.0 I get just over 13 GB/s. With the theoretical max being 16GB/s it's what I expected.

    Is it just me or this seems like a pointless test? Only to feed curiosity really :p
