(don't know if the issues are more with the game engine, or with OpenGL in Windows), that could maybe possibly help with the DirectX 11 requirement (don't know what version OpenGL support would be required).
Some other engines allowed to choose shader model. Actualy it is the main differnece beteween 10 and 11. Therfore a game made for DX11 use by shaders of DX10 runs on old graphic cards. As long as you have DX9 rendering core tuned, that would be more stright forward solution then OpenGL API.
Anyway there is about 17% general performance gain between DX9 and DX11. So you could buy a used old graphic card for 50Eur you get much better result. For example Nvidia gtx 570 on E-bay. In fact its a price of a full game.

Well, you could keep your kidney. Send me your girl-friend for a weekend. I will send her back with a card you need.
