Intel i7-3930K $550
Zalman CNPS12X $87 ($15 rebate)
Asus P9X79 $255
Mushkin Enhanced Blackline Frostbyte 16GB (4x4GB) DDR3-1600MHz CAS9 1.5V 993995 $87
Seagate Barracuda 1TB 7200RPM ST1000DM003 $98
Intel 520 Series Cherryville 120GB $165
Asus GeForce GTX 680 2GB $508 ($7 shipping)
Antec Eleven Hundred $100
Windows 7 Home Premium 64bit SP1 OEM $100
Asus DRW-24B1ST/BLK/B/AS $20 ($5 shipping)
Total: $1975

With the following PSU:
NZXT Hale90 750W 80Plus Gold Modular $140
http://www.amazon.com/HALE90-Power-Supply-Modular-HALE90-750-M/dp/B003YFIUEG
The Corsair HX 750 is the same price on Amazon last I checked and there's not much to choose between them at the same price.
Which brings the total to $2115

Which leaves ~$800 to get monitor (which I don't have enough knowledge about to make a recommendation, but you should get a high end model), peripherals (personal choice), other software and maybe even a second GTX 680 straight off the bat, depending on spending a small enough amount.

Total came to just under $2400, but this is a fantastic system that will do as you please. I know that the motherboard isn't Asus, but it is still a very good motherboard with the latest technologies. You can also spend $50 on Word from Newegg or buy all of the range for $100 (University edition).
