Is this worth it? Dell Special Alienware Aurora!

Today was slow at work, so I spent it looking for a new PC as mine is rather aged. My current build worked amazing in games such as Warhammer and World of Warcraft. Now I'm playing AION and it seems a bit more demanding. I feel its time to upgrade anyway.

I have experience building computers, but I feel safe in the decision in buying one this time around, especially since I think its a great deal! Now, to get your opinion on it!

Dell has a 24hour sell, 11 hours remaining as of now, which include an alienware aurora. (Oh i know, not worth paying for the name, but its on sale!) Here are the specs so far.

I want an updated build. Do you guys think its a big enough jump between what I have and what I want? Is the dell special a good deal? And for any AION players, will this rid fortress siege lag? (Main purpose of the build)! Also, I have a limited time for the offer, so reply quick Thank you!

If you have experience building, why not spend that money wisely?
You would probably get the same parts, but at least you could buy good quality parts.
With Dell you'll probably get some generic parts, or at least not the same quality of what you could buy.

I was actually preferring AMD over Intel this time around. I had this setup in mind, and it would be really cool if you guys could help me narrow it down to what will work. I spend ALOT of hours in front of my computer, gaming is the main objective. I do not need a monitor, keyboard, or mouse. And I can use any existing parts from my current build, if needed, and possible.

As for the case, I dont need anything fancy, just big enough to hold everything with good air flow. Hope I didnt miss anything!
