My computer is about 8 years old and I have recently started playing World of Warcraft. Being the giant game that WoW is, my computer cannot handle the game and usually doesn't run over 10 fps. Since it is such a big problem I decided I'm going to buy a new video card, the only problem being I don't know what would be compatible with my computer since it is so old. My system model is MICRO-STAR INTERNATIONAL CO., LTD, and my operating system is Windows XP Home Edition Service Pack 2 (build 2600), and the video card that came with the system (the one that I still have installed) is NVIDIA GeForce2 MX/MX 400. So I was wondering if a video card like this one http://www.newegg.com/Product/Product.aspx?Item=N82E16814150247
would be compatible with my ancient computer. If it isn't could you please maybe give me some suggestions as to what video card I could buy that is more of a computer gaming video card.
