I7 - that is a gaming PC, not an editing PC.
Video Editing software does not use the video card enough to justify anything over GTX 760. The gains are non existent.

Even GTX 650 does not fall far behind from the 4-5 times more expensive cards.
If you use Photoshop or After Effects - AMD is not an option. Both are RAM amount and RAM bandwidth hungry monsters. AMD platforms have a considerably less bandwidth than Intel platforms.

Also, FX 8350 can catch up to 3770k and 4770k in rendering, but not during pipeline work. A lot of the functions in that software is low threaded, and the FX feels sluggish. Also the 8350 is miles behind the new 4790k
P.S I am a 3d modeler, animator and compositor.
