PC Upgrade (R5 1600 + GTX 1060 or R580)

Hi guys,

I am trying to upgrade my very old PC, which means, I'll have to upgrade the mainboard, CPU, GPU and RAM all at once. So I wanted to run my system specs by some people that knew what's up :) So eventually it's between: https://de.pcpartpicker.com/list/MjTPBP https://de.pcpartpicker.com/list/XWgzTH

Of course I'm open to suggestions, but I wouldn't want to go much higher in price. (the r580, i found at the same prize as the 1060 here). What do you guys think of the i5 6600?

thanks!
