Possible Video Editing Rig

http://pcpartpicker.com/p/esyi

This is what im considering for my next system

Uses:
Video Editing (using CS5)
I do some Mech Engineering on the side using Inventor Pro and some other Autodesk products (CAD, Rivet). This is not priority one as i don't want to max out my budget with an expensive workstation class card
Will be putting up BR movies on a 46" LED while working off the monitor listed in the build above

Considering a scratch disk for editing

I already have a WD 1.5TB media drive

What are the opinions on compatibility and the quality of the build as it relates to editing video on CS5.
