    I believe they are capable of running dx11 games, but will not be able to utilize certain dx11 features.

    No, it's not. DX 11 is backwards compatible though, which is probably why it's showing up.

    From my understanding, Directx 11 is a component of windows 7, so if you are running windows 7 you have directx 11. That does not mean your GPU is able to support directx 11. Basicly you have the software to run directx 11 but you dont have the hardware.

    Exactly. However it will be a couple of years before games use DX11 properly. DX10 has yet to be fully utilised, with modern games still looking pretty sweet under dx9.C

    from amd website it says that 4670 can play dx11 games and utilize most features, it think the only one that won't work is tessalation, but we will still benefit from dx11 better support of multithreading.

    The Mobility Radeon HD 4670 is DirectX 10.1. If you have DirectX 11 installed (default in Windows 7 or Vista with platform update) it will show up in dxdiag as 'DirectX 11' however, it won't run games in Direct3D 11 mode (even though for many years the tessellation feature has been on ATI cards but other features are not necessarily present). Generally speaking, the differences are negligible. Tessellation (if it becomes widespread) is supported by almost all modern GPUs (Radeon 2000 series and higher), albeit it the same implementation as DirectX 11. OpenGL has had tessellation support for many years...

    The DXDiag shows what version of DirectX is currently installed in your system. Not with what DX version is your GPU compatible. You have the DX11, but you don't have a DX11 hardware, and therefore you won't be able to run any DX11 games.

    In dxdiag, if you go to the 'Display' tab and look at the 'Drivers' section, you'll see that the 'DDI version' is only 10.1. This is your configurations actual Direct3D level.

    DirectX is not just graphics, there are other parts to it.
