I have upgraded my operating system from Windows Vista to Windows 7 only a couple of days ago and now I have realized that Windows 7 not accepting AGP video card. I have decided to buy a new video card but, they can adapt to DIRECTX 9 only. But, I have installed DIRECTX 11 currently on Windows 7. I cant understand whether DIRECTX 11 is compatible with Windows 7 or not. Can the new cards not run on anything other than DIRECTX 9? Please suggest some solutions that may help me to remove this conflict of DIRECTX 9 with DIRECTX 11.
