Please help with deciding what will be my next PC!

Hello to all,

I am determining what PC to buy next and saw that one processor from one computer had 1.86GHz, 4 MB L2 Cache, and 1066Mhz FSB, while the other had all the same except only 2MB L2 Cache. Therefore, I was wondering how much difference this 2 MB of difference would make in gaming and performance. Furthermore, these two PC's are the New Dell 720 Black and the other is the Dell XPS 410 Desktop in case anyone wants to tell which one is better (720 Black is brand new so good luck). In addition, it isinteresting to note that the 2MB L2 Cache processor is on the more expensive model (720 Black) which to me doesn't make much sense. I was wanting to buy the720 model but didn't know if it was even a better computer than the other. Your amazing insight would very much help me because I am very much ignorant when it comes to the technical aspects of computers. Thanks.

The 720 is 400$ more with 2MB less in cache. Doesn't make much sense huh?

Sure here you go. Thanks for your help.
