Thanks for all the replies guys! I'm specking my future system, so I'm trying to look at the choices from a lot of angles, including what might be down the road.
Much as it pained me, I bailed on an AMD config early on because of 1) performance, 2) dead-end mobos for their latest cpu/socket, and 3) there were a total of 9 mobos for it. With intel this time around, I'm literally spoiled for choices.
If Intel had come out with a quad with 4Ghz base at the 5820K's price, I'd definitely be decided on X99 / 2011v3 - that's my tipping point to absorb the +$180 platform (Mobo and Ram) hit the X99 requires.
If something like a hex core around the 4790K's speed might be in the works for the 1150, then that's a point in favor of picking that platform and waiting for it, comfy like with a 4690K!!
