Also, your thread has been moved to MAIN Hardware Zone Area because of:
1. Potential Discussion
2. It was not a Buying/Selling query neither a Hardware Problem related query.
on a personal note - i wont recommend spending more on i5 / i7 coz of weak gpu -- again the performance gain is negligble even if gtx-260 is included unless its a heavy weight laptop such as alienware etc.though ur choise i would still recommend only the xps to ppl -- cost effective / cheaper / good value
