Well intel will consume way less power than the fx-9590 and fx will output way more heat than i7 and you will need some aftermarket cooler to keep it cool, also i7-4770K can be easily overclocked and it will perform better in gaming than the fx, I think the only area where fx is better than i7 is some kind of video encoding and some large multi tasking, but I definetly would go for Intel.
