Either go with the second one or the last one..

EDIT: Dont read anything I said, heres a simpler explanation.

Scale Goes: Okay/Good/Great/Awesome/Amazing
First One: Okay Speed
Second One: Awesome Speed
Third One: Great Speed (But more memory for your music and stuff, but not that much of a difference.. REALLY not worth extra 100 dollars)
Fourth One: AMAZING Speed

The first one only has 2gb of Memory (Crap) most vista computers take up like 1.4 from vista itself(As in vista running on your computer), so 4 is a good number.. The good thing about the third one is that it has more memory, but when you look at the memory from the 2nd and 4th.. Its 250, compared to the thirds 320.. Which 250 is enough already..

The only difference from the second and the 4th one is the processor, the processor is how fast it is, and as you can see the models are quite far.. 3400 and 6600.. :D Gl
