You can attach it under any flat surface, probably your table. It doesn't come with a stand but instead a rotating patch kind of thing to tightly secure it under a flat surface.
I think you can use it in GTA though I haven't tried it personally. For BF3 even if the wheel is connected to the USB port while in-game, your crosshair will always point towards the sky and you won't be able to control your mouse.
