You won't see a performance difference in games. 980x will only stand out if you use apps that able to make use of its cores. Eg like quad threaded applications.
What will make a difference if you get a good gpu or add another.
thats what makes it go wrooooooooooom fast lol
Take away the Turbo and you sit with a expensive VW
still won't perform better than he's current setup. What will make his pc perform better is to put that ssd on a Pci-e card in a raid setup. He won't have use for the 980x unless he's into video editing in a huge way
