I am not familiar with the hardware requirements of Alice: Madness Returns, but after looking at what you got listed, that configuration is not a suited for gaming. About the only positive aspect is that you have a graphics hard, but it is a less-powerful economy model. It will definitely help, but the lack of RAM and weak CPU are your problem.
You may be able to skate by on the RAM, so long as all the graphic quality settings are set a little lower, but I personally would look into a processor upgrade. If you have the extra cash, try to upgrade the RAM to at least 3 or 4 GB, it will make a world of difference, not just for gaming, but even normal stuff like compressing files, multitasking, etc.
