I'm buying my first pc -a Dell- and i dont want to spend the extra 200 on the ati 9800 (i know, ati is the better card, but i dont have the cash), and the nVidia FX 5200 comes with the computer anyway so, will this card be enough power to play games like call of duty, moh, americas army, etc??

..ps.. the system i'm getting comes with a p4 2.4ghz, 256ram, etc

thanks
