in terms of video editing you want more cores and faster processor, the FX-8350 runs at 4.0 ghz and has 8 cores, and it naturally overclocks to 4.2 ghz while the i5 has 4 cores and does not support overclocking while only going 3.4 ghz
I would go for an amd processor, I'm using the fx-8350 which has a 9,022 grade on cpubenchmark.net while yours has around 7,000, also its only $200. But thats just my opinion, your graphics card is good (that's the one i'm using)
