Sorry, that sounds like a laptop to me? But even so, not really designed for gaming, but should play COD 1 and 2 ok. With the NVidia cards, you can sacrifice quality for speed. To do this, right click on your desktop and go to Properties, Settings tab, Advanced followed by your GeForce tab. This location may vary slightly between versions, but can normally be found under 3D Settings > Adjust Image Settings. Change to Customize or Use my preference emphasizing, and use the Performance/Quality slider below, and drag it as far as you can towards Performance.
