I need help picking a gaming computer, help?

The second setup has a better processor, but the video card on the first one is better. The 2nd set up has an onboard HD3200 and a HD3450 in the PCI-E slot. I think you are much better off with the first one. To play those games I think you should have at least a GeForce 9600GT though. If you build your own pc it would be best because you can decide what to put for each component and it's cheaper.
