Been watching this thread with great interest
I'm due a system upgrade with my 3570K getting a little long in the tooth now, although to be fair still going strong with a mild OC since day one.
If I upgrade to Zen, which I'm seriously considering, it would be nice to make sure it lasts a good few years again, although hopefully the new competition that AMD are bringing will mean progress stops being so stagnant.
At the moment although I'm tempted to jump straight in for a Zen I think its probably sensible to wait a couple of months for prices to settle and availability of chips and boards to improve. Gonna be hard to watch you lot showing off your new shiny builds though!
