Ive seen 2 dates for SB-E. They most widespread is saying Nov.14, and I seen one today that claimed Intel said the day after Thanksgiving.
Now, dont take that for 100% fact. But it does seem it should release somewhere in that ballpark.
Also, there was supposed to be a Quad Core version (the i7 3820) startign at around $295.
Last rumor I heard, it was being delayed until Q1 next year, but I cant find anything concrete on that. ATM, just a rumor.
There will also be the Hexacores, starting at $584.
At any count, being as its so close, it may be worth looking into.
Will require a slightly more expensive x79 MOBO, and as carwiz pointed out, Quad channel memory.
Was going to build one myself, but changed my mind on it.
