It depends what you configure them to be on the Dell website. I5 is better than I3, DDR3 ram is better than DDR2, SSD HD's are better than disk drives etc.
The XPS is made more for gaming and is a far better computer. It may be more expensive than the Inspiron but it comes with extras such as an aftermarket CPU cooler and a case that makes repairs and upgrades easily. The questions is really if you need it or not. If you don't plan on using it for gaming, video editing or other high demand process, you should save the money and get the Inspiron
As of June 2014, the Dell Inspiron 520 is not good for animations. This was a gaming laptop that was released in 2007.
No not the best for GAMING But good for media or anything else. Laptops that dont have a certain games processor wont give you the best gaming.
The Dell Inspiron is a laptop, therefor cannot accept any other gaming video card, except for the one that is prebuilt it. If you really need this done, you can purchase an external moniter and Vidock, and use those (If your laptop has an Express Card Slot).
From what I have seen I would say that the best computer for online gaming would be the Dell Inspiron 1720. It doesn't freeze up or have what gamers call "lag."
Many Dell computers are not very good at gaming, and the n5010 is within that "not so good" range. If you are looking for a gaming computer, I suggest something that cannot get viruses as easily. Such as a MacBook Pro, AlienWare, or iMac.
The Inspiron 17" 5000 Series with Intel i5 processor at $649. http://www.dell.com/us/p/inspiron-17-5749-laptop/pd?oc=fncwh2434s&model_id=inspiron-17-5749-laptop

The main difference between these two laptops are the price and the quality. The Dell laptop is more expensive, but also of much better quality. The Lenovo laptop is for basic operations, as the Dell is made for gaming and lots of media use.
