Just wanted to say that I made a list of all the Direct X 11 Games that are out or confirmed. Maybe this will justify spending the extra cash on a new card. or maybe the opposite!
Games That use DirectX 11
All these games use the latest version of Direct X.
Currently only GTX4xx and ATI5XXXX cards can render 11, as well as only Vista and Windows 7 can run it.
List is in no order.
