If people can resist Kaby and the corresponding chipset it will help pressure Intel to up the performance mainstream to 6 or 8 cores on a more aggressive timeline. That said, let me make a case against upgrading from anything Sandy Bridge (2xxx series processors and 6 series chipset) or later: this platform offers very little if anything new. Same max core count, same dual channel DDR4 memory, same PCIe slot configs. The only new things are this supposed Optane support (which may not be exclusive) and native USB 3.1, though many current boards already have USB 3.0 and 3.1 even from Intel. Optane itself has been listed as having initial capacities of 32GB... pfft. Cross your arms and sit on that cash people.

So this is Tock? i'm waiting to upgrade my z77 and 3770k.. should i wait for the next tick? or next tock?

My excitement cannot be contained in my mortal vessel.

Well this Tock is more Motherboard feature related. If you don't plan to use any of the features and hardware mentioned in this bit of news, then I would wait to upgrade if you are fine with your current rig power wise. Don't upgrade for the CPU...upgrade for the MB features, again IF you are going to use the new pcie SSD by intel and want rapid storage technology to drive it. Of course there is a bit more than that to it, but that is the main selling point. Faster SSD's.

The cpu/chipset also has full hardware support for 10bit h265 encode/decode so will make a much more efficient HTPC. This decode previously required an external GPU. While I don't expect to use an Optane drive for several years (if ever) it's a nice future proof feature. It will also increase the PCI-E lanes to 24 from 20 on 100 series chipsets/skylake CPUs, which will be nice for current and future M.2 NVME drives. I'm upgrading from an ancient Westmere i5-650 so I'll be getting a ton of new features (usb 3.0/3.1, DDR4, PCI-E 3.0, etc etc). My current Haswell gaming rig will be fine for another few years. Really the only reason to upgrade these days are additional PCI-E lanes, or chipset features, unless you have specific workloads that necessitate an upgrade. Simple single threaded performance was good enough for almost everything years ago (and still is even with my Westmere). One thing I have noticed is a lot of new games requiring Sandy/Ivy or later CPU's in their minimum requirements, which to me is ridiculous. However we're going to get a point where even everyone's mighty Sandy will need to take a step aside. Don't think we're there quite yet though.

AVX. If the previous Core CPUs had it, most of them would be fine too.

Honestly people rather wait for zen to see differences and optane will cost you an arm and a leg and your soul.....if things are too expensive go bang for buck...and stop feeding these rich cu!@#nts... I have been a intel fan for many many years since amd 64..but a little excited for zen overclock. BTW: zen comes with features build into the cpu
