Thanks. I've been agonizing over the decision between the 5960X and the 6900K. The 7700K also seems to overclock quite well ... obviously with 1/2 the cores though. I don't know that I'm willing to wait on SkyLake-E thinking that it may be a 14nm bust like Broadwell-E.
On the other hand, the rumors seems to indicate that Intel is pulling things forward a bit which may be an indication that they had to put down the popcorn and get up off the couch and do something once Zen dropped.
