Need Help on $2000 Video Editing Build

[TStrausbaugh3203450]

I am going to be building my first computer at the end of the year. I will be editing HD video and want to edit video for a career, Youtube content creator. This is my first computer and i would appreciate help from the community. I am 19 and have saved up $2000 for this computer. I will be using either the "Internal Graphics 4000" built into the CPU or maybe a GTX 550 Ti for graphics if i decide to run dual monitors. This is not intended to be a gaming computer, This is meant to be a video editing computer. I have done my homework on the parts but i know that i should still get advice from other people. Thank you again for helping / giving your opinions on my build. Also is this Overkill?

-I will be waiting till the release of Windows 8 to start my build.

Software:
Video: Sony Vegas 11 Movie Studio Platinum
Photo: Photoshop CS 5.5
Audio: Audacity

Hardware:
Corsair 650D
Intel i7 3770k

Corsair H100
Corsair Vengance 16Gb (2 X 8Gb)

WD 2Tb Caviar Green Hard drive
Hauppauge Colossus

Reasons for Parts:
Case------------Mid-Tower, Side panel, Cable Management Gromets, Looks good
CPU-------------Will prob Overclock to 4Ghz..
MotherBoard---One-Click Overclocking. Z77, SATA3, USB 3.0, T.U.F. Board
CPU Cooler-----I dont want to upgrade later, I am nervous about messing with the cpu cooler too much so i'm just going to start with H100
RAM------------So i can upgrade to 32Gb down the road
PSU------------Plenty of overhead
SSD------------Boot Drive / Programs
HDD------------Storage
Cap Card-------Record Gameplay, Music, Movies
OS--------------Better support for Dual Monitors

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

**Probable Future Upgrades:
60Gb SSD Cache for Hard drive

More Fans
Ram upgrade to 32Gb
Dual Monitors
EVGA GTX 550 Ti

Any help from the community would be great!
