dell dimension E520 for gaming

[Mr. T]

So my brother wants to get a new dell, he wants a 2007fp, and he wants to be able to play games like Civilization IV at the highest settings. He's looking at dell's XPS systems but I think a customized Dimension would be good enough plus they are %20 off right now.

So I have a couple of questions.

Is this video card good enough? They offer a ATI Radeon X1300 Pro for $41 more. Or should he buy a different card and install it himself, if so is there one you guys recommend?

Which is better for gaming(he does not play poker) the 2007FP or the 2007FPW?

Thanks in advance here are the specs:
