Ugh... why is it that all big name system builders just want to sell you stuff you don't need and make their hefty profit? I by no means added up anything, so this isn't official, but I know as a system builder myself, that I could EASILY build a system of this magnitude for at least $800 less. Not to mention I would change a lot and advise you on other things.
What is the deal with all this extra stuff:
Round Cable Upgrade for Optical Drive
Vigor iSurf II Hard Disk Drive Cooling System
1200 Watt Thermaltake ToughPower Power Supply
I don't see a point to the "round cable upgrade", nor the hard drive cooling. You will already be running like 6 fans in that case, so heat should not be a problem. Plus, the CPU, watercooling, etc is only ever necessary for the "benchmark crusher" systems. If all you need is a computer for gaming and editing, you would be good with 1 GTX 280, air cooling, 4GB DDR2 (since DDR3 is only necessary for Nehalem and shows only minimal gains over DDR2), Corsair 750W power supply, and Windows Vista Home Premium 64bit.
There is absolutely no need for any of the extra stuff I mentioned. Plus, with a mild overclock, you could buy the much cheaper Q9650 and have it easily compare or beat that CPU.
