I don't think the fx9590 is 'dead' , gigabyte has released a new motherboard for it eventhough the zen is coming out in a month or so , you can find that motherboard on amazon , why would they issue a new motherboard for that socket if it was supposedly dead ? apparently it has its own market and people are satisfied with it , if you use it with water cooling there shouldn't be really an issue , only it consumes lots of power
