Fx 8320 + gigabyte ud3p + decent cooler, if you're on a budget. The 9xxx series is just the fx 8320/8350 overclocked. Just overclock it yourself and you have yourself a fx 9xxx chip.
Video editing would do better with the fx 8xxx chips, if you're doing a lot of video editing/rendering then you'll do better in this area. The i5 will do better in gaming though. With the fx 8xxx chips, your'e sacrificing single thread for multithreaded performance.
With the budget of a 9590, you should be able to go with an i7 or xeon. Xeon if you're not overclocking and i7 if you are.
The price you pay for the 9590 and a compatible motherboard is more expensive than just going with an i7.
