A few things I noticed on the parts list that you should reconsider
The CPU - Get an Intel cpu, if you don't mind spending that kind of money on a computer than you may as well get an Intel cpu like a i7 3770k or something. You've obviously got performance in mind because...
The Video Cards - You selected 2 highest-end video cards, which is fine if you've got the penny to pay for it, but one should be more than fine and save a lot of money
The speakers - 600w PMPO subwoofer speakers? Because it says "pmpo" you can almost certainly be sure that they are probably 10w rms cyber acoustic speakers. Look up what PMPO means, it's a pretty useless number. Whatever you're paying for them it's too much, you can pick up some cheap logitech speakers at walmart and be much better off.
The power supply - With just one video card you won't need 1000w and could do with 700/800w and still have more than you need. (someone verify this for me)
Also, do order the parts individually and build it yourself, it'll come out much much cheaper.www.pricewatch.com
is a good place to look up places selling the parts for the least.
If you're adamant on not wanting to build it yourself a good place I've done business with before is www.portatech.com
. They are very reasonable with most of their prices but you may want to get the video card separately to save a little.
