    So I'm starting to see motherboards and graphics cards with / supporting PCI-E v.3. I can see the numbers - double the bandwidth. But my question is whether this is actually making a difference? I hadn't realized this could be a bottleneck. Is it a bottleneck to have version 2? What do you have to do to make PCI-E v3 necessary / useful? I'm guessing it would have to be a pretty powerful rig, or am I wrong and this is already useful to ordinary people?

    Nah, I don't even think any of the new cards anywhere near max out v2 yet.

    v3 is just a marketing thing at the mo.

    *sound of 100s of experts typing to prove me wrong*

    PCIE 3.0 is must have if u go 3 way SLI, as it shows huge gains. other than that no, maybe big daddy maxwell or Pascal will require PCIE3.

    PCIe isn't maxed out by GPUs afaik. Might be handy with certain PCIe-SSDs though, they might be faster, or am I wrong?

    That's kind of what I thought. We have some people with pretty amazing systems here though. Is anyone actually using and needing this, here?

    I haven't got an pcie 2.0 board to test the diff although x4 x8 pcie 3 vs x8 x8 pcie 3 is next to nothing from my testing of two pcie 3 motherboards. and that is testing with 2 x r9 290x's

    boards I have and tested with are the

    Asrock H87M pro4
    Asus Maxiums VI Hero

    on the 23/02/14 http://www.3dmark.com/3dm11/8021661
    on the 23/08/14 http://www.3dmark.com/3dm11/8643793

    maybe it was the ASRock H87M Pro4 motherboard (was only crossfire motherboard they had in shop until my maximus vi hero turned up)

    few more tests
    AMD A10-6800K AMD Radeon HD 7870
    http://www.3dmark.com/3dm11/8635962
    AMD A10-6800K AMD Radeon R9 290X
    http://www.3dmark.com/3dm11/8621475
    AMD A10-6800K NVIDIA GeForce GTX 760
    http://www.3dmark.com/3dm11/8013255
    AMD A10-6800K AMD Radeon R7 250 DDR5 version (R7 250 works in Dual graphic's mode boosts the A10-6800K's gpu around 2-5 fps faster although if I run the R7 250 by its self its much smoother game play) sozz about edit (late nights)

    Thanks for sharing that. That guy is great!

    And actually I did learn something. I had no idea that a card would still work in a smaller slot than it was specified for. Really useful video all round.
