What parts should I have in my Alienware?

Well it will be a beast of a computer but at the same time its a major overkill in a lot of ways. 750G HD seriously i have never gone over 40G of memory and i had 10 major MMOs on my computer. Don't get me wrong if I had the cash and didn't know how to build my own PC i would love an Alienware but before you drop that much cash you should check out www.tigerdirect.com you can find some killer deals on gaming PCs there
