Looking into it a bit more, it looks like if you tweak the settings a bit it should actually fix any fps issues you may have from liftoff. I haven't tested it yet but it sounds promising if you open the graphics settings config file and set vsync to false. Your CPU does support SSE 4.1 as well, so you won't get the immediate crash to desktop issue a lot of people have been having.
To access the config file, go to the folder you've installed the game to, then into binaries, and into setting. Open the file 'TKGRAPHICSETTINGS' with notepad, and find the line <Property name="VSync" value="true" /> and change that to false. Provided you are seeing FPS issues if you do try it out.
