That graphicscard (FX5200) is really not steered towards HighEnd gaming, it should be able to run the newest games resonable framerates at low to mid resolution, but its not impressive!
If you are builing the PC yourself I would recommend losing one of the HDs and use that money for a midrange graphicscard e.g. Nvidia 5900XT or even better a Radeon 9800Pro (i personnaly recommend
HIS Excalibur IceQ )
