I have never found any of the extreme editions worth it. Why pay $1000-$1500 for a CPU when they will come out with a new one that will beat it in six months for $300? 
If I had absolutely everything I ever wanted, the entire world was fed clothed and sheltered, and I still had $1000 to waste I would still not buy an extreme edition CPU. 
The 940? Yeah I can see some people paying for that. Not me, but it isn't outrageous like the extreme edition.
