Screw compatibility lists.
Get a Z77 and i7-3770k instead, also you don't need an i7 for gaming. i5 does fine. I have no idea if you need all that horse power just for editing though.http://www.anandtech.com/bench/Product/287?vs=288
As you can see it has very similar performance for $100 less lol. Go with an i5-3570k if you're going with an i5.
650 watts will be good if you're not going to sli.
Get 8gb of ram 2x4gb 1600mhz.
You forgot Windows 7 and a hard drive (128 is literally nothing.)
