Are these good/different?

Hey, first time posting. I'm currently in the market for a new laptop, and this one caught my eye: http://www.newegg.com/Product/Prod [...] 6834215371

It seemed like a great bargain, and the best I've found. When I googled it to see if it was the best price I found some odd results. I found the laptop I had looked at, but then I found what looks like the exact same computer i a different color for $100 more! Can someone tell me if theres any difference between the two:

Also, any opinions on whether this is a good PC or not would be much appreciated. I mainly want it for gaming, but because I might be going to college in the near future, I'm not sure a desktop would be the best idea. If theres a better laptop for under $500, Id also be interested in it.

Thanks in advance

PS: sorry I'm posting twice, I wasn't sure where this should go
