Nicely built. I would step up to the next best GPU, if you would like this baby to last. I have learned to never go with Intel after what happened to my Dimension 3000. It's absolutely useless, because of the integrated GPU.
Better deal than Dell...there aren't really any sites that I know of. Even Newegg is more expensive for most laptops.
I would stick with the CPU you have now.
Your order will probably be delayed, like a lot, maybe a month.
I ordered an Inspiron 1520 on the 17th of last month, and the "estimated ship date" is on the 28th of this month.
Message me if you have questions.
