For video editing you really do not need GPU like that 650/660 is fine. What you need is memory 32GB is not overkill, it is good to have.
Better have 2x SSD to raid 0 and one smaller SSD for cashing. Then it also good to have one HDD to material what you have not been edited and one for edited material. This makes read and write speeds go much faster. Also it is better to have raid set for HDD:s.
GPU is only needed for gaming. No real benefit in video editing work. Depending what programs are used.
Look here some specks:

Cheaper option is take intel xeon 1230V2 and B-75 or H-77 Mother Board. But if this build is for proffessional work. Then best way to go is 2011 3930K
