Well you cant go by that, sorry! Mine says dx11 also, but it is not a dx11 card. It only supports dx10. If you want to be 100% sure that it can run dx11 games your going to have to google the exact model of graphics you have, or the computer name, and see if it supports dx11, or try running a game in dx11 mode(maybe a dx11 demo if there is one out there?). Though you can install dx11 it seems, it doesnt mean you can run a game in dx11. Thats my best guess., because like I said I have a gtx275, and it is only dx10 capable
