Are these PC components compatible for a descent video editing rig?

I want to know if these components are truly compatible before I order and start assembling. I will be using this built primarily for video editing, media encoding, and DVD authoring with Adobe Premiere Pro CS4.

It all comes out to under $1000. I am open to ANY suggestions, but I do want to keep the price as low as possible.



Thanks

jack|||I think your paying too much... I would give GPB a shot, never hurts to get a free quote price to see what they can build you.

Gaming computers and video editing rigs are pair for pair. They both require high performance parts.
