Hi, Im brand new here and really dont know much at all about computer hardwear, so I need some help. I just bought this game(Civ IV) and it seems my video card isent good enough to play it. Now heres the problem, I have no idea what info is needed to figure out what kind of video card is compatible with my computer, and no idea what any of the abbreviations mean on the million different cards. I have an Insignia D400a from Best Buy. My question is, what information do I need to obtain in order to figure out what kind of card will fit, and how do I get that info. Any and all help is greatly appreciated. Thanx in advance, Eric.
