My Res for all games is like 1024x760 at the moment and i'm not lying there would be not point posting this comment if i was the website is to help other users out, and i'm not wrong about my computer because it's custom built, and i even used DxDiag to check the system.
Ps i didn't say i play all the games on ultra, i can only play Skyrim on Ultra, battlefield and Arma II is only on high and i bought the graphics card myself so it's definetly the 5400 series.
