If I were going AMD I would go for either of the following CPU's.
AMD 8320
AMD 8350
AMD FX-9590
These are the best CPU's from AMD at the moment for gaming + video editing.
AMD will be releasing some new CPU's in 2016 with the "Zen" architecture if you want to wait till then however.
Although the "Zen" CPU's will be only supported on FM4 motherboards which supports DDR4, this will be a new socket type so take this in mind.
