  1. Yes, they are backwards compatible.

    And the cards should work fine together with no problems.

    Edit^ didn't see the part about bottle-necking. But they should still work great together.

    Nah it wont bottleneck, and yes they are backward compatible, Even a single Titan X on an old PCI-E 1.0 x8 slot wouldnt bottleneck it.

    Even 2.0 and 3.0 are More than enough bandwith for single cards 5 years from now provided they were at-least x8.

    To add to what this guy said ^. The new USB type c connector actually can transfer over a PCIE x4 bandwidth.

    I say this because EVERYBODY has graphic amplifiers that either use proprietary, thunderbolt, or USB type c for the amplifier. And they all work great, even with a titan x in the amplifier.

    Makes you wonder why we even have PCIE 3.0 and 2.0 if 1.0 speeds are still great for modern games. lol
  4. Typical PC marketing with things like PCI-E and USB, they tend (with most but not all things) to add way more bandwith than nessesary. however its not really a bad thing, cuz that means it will be a Looooooooooong time before they are able to even saturate and old x16 PCI-E 1.0 slot.
