Computer for video editing?

I need to build a low and high end computer for video editing for an assignment. One of the marking categories is compatibility, which I'm unsure of in this build.



High End Build is:



Motherboard: Gigabyte G1-Sniper ATX Motherboard



CPU: Intel Core i7 990X



Memory: Corsair CMX12GX3M3A2000C9 12GB (3x4GB) DDR3



Video Card: EVGA GeForce GTX 580 3GB



Primary Hard Drive: OCZ Vertex 2 3.5in 120GB SSD



Secondary Hard Drive: Western Digital Caviar Black 2TB WD2002FAEX



Optical Drive: ASUS DRW-24B3LT 24X DVDRW LightScribe



Sound Card: ASUS Xonar HDAV1.3 – Unsure if a sound card is needed, will the motherboards integrated sound be enough?



Case: Antec Dark Fleet DF-10 Case



Power supply: Corsair AX750 Gold Power Supply



Mouse: Gigabyte GHOST M8000X Gaming Mouse



Keyboard: Razer Dragon Age 2 Black Widow Ultimate Mechanical Keyboard



Monitor: Samsung MD230X3 Multi-Display 3x23inch cPVA Panels



Speakers: Logitech Z906 THX 5.1 Speaker System



Operating system: Microsoft Windows 7 Professional 64bit with SP1 OEM



So that's it. Will all that work with each other? Do you have a suggestion?



Thanks. :)|||Yes it will work



you can avoid the sound card since the G1.Sniper on board sound solution is OK|||you would be better off with an amd and ati cards and crossfiring
