You already know that is the FX-57... The FX-57 is undeniably the fastest consumer CPU available for a single task (gaming) right now. That being said, it is extremely expensive for the performance and a poor value. Personally, I think going for an Athlon 64 X2 is a better way to spend your money (obvioulsy from my sig) because it will allow to play games while doing other stuff in the background. The fastest X2 is the 4800+, but it's literally double the cost of a 4200+ and doesn't offer anywhere near double the performance. I am really happy with my 4200+, and while I did spend a decent chunk on it, it wasn't anywhere near $1,000 US.
Of course, this shouldn't matter, but it seems to matter to you for some reason.... You seem to not want to be pegged as a n00b, rich kid, mama's boy for buying an Alienware, but yet you are compelled to build a rig with n00b, rich kid, mama's boy parts... Why not just let your parent's buy you the Alienware, and learn about computers/value on your own while you also get to enjoy the Alienware? You'll be going to college soon, and your life/standard of living will most likely change drastically in a few years anyway - enjoy the salad days while you can. The Alienware will be a really nice computer, just a bit over most people's budget. Then again, the parts you are looking at are also way over most people's budget. The main reason most people would say anything negative about your Alienware is because they either aren't willing to or are unable to afford one. So, if someone is willing to buy you one, take em up on that offer. As much as I like building my own and saving some cash, I would have nothing against someone else buying me an Alienware. Hell, I'd even get the cheeseball Star Wars one with the goofy paint job...
