That game is not worth the money, also your team members have no AI, their movements are completely scripted. They do not kill any enemy units in single player, if you don't believe me then using the PC version, give your self unlimited health, then walk out into the middle of a battle, your team will shoot constantly but will never hit a single enemy, meaning they are just there for show.
I have a GTX 460 (overclocked) and a Phenom II x6 1075t (overclocked)
The game ran fine with all settings maxed out.
Also, the graphics suck compared to battlefield 3, they used textures with very little detail in comparison, the HDR lighting was done poorly (many highlights were clipped to gray)
