Is AMD FX-9590 worth it to get or just get a FX-8350?

Hi,

I'm getting cpu + motherboard. I can get either:

FX-9590 or FX-8350? 

I know about the FX-9590 power consumption + heat + more powerful mobo is needed, is FX-9590 still worth it you think? or just go for the cooler & cheaper setup FX-8350 + AsRock 990FX-Extreme3? Any significant difference in hashcat? Thanks for your input.
