here is some random x299 info for anyone interested. note- these are just from news stories i've read, so i cannot confirm these. 1) intel decided to save some pennies and therefore skylake-x will not have soldered on IHS's. so in addition to very high watts when overclocked, folks are reporting very high temps. 280-360+ mm liquid cooling may be more commonplace for anyone overclocking. 2) intel has been changing chipset compatibility with xeon cpu's, removing xeon support from main-stream platforms. this may follow with x299 and it might not support xeon. this may not be a big deal for buying new, but may remove upgrade options from cheap used server xeon's. 3) only the 10-18 core cpu's offer 44 pcie lanes. 6 & 8 core cpu's will offer 28 lanes, while the 4 core models offer 16 lanes. many x299 motherboards appear to only offer x16/x8/x4 with the 28 lane cpu's, but there appear to be a few that offer x8/x8/x8. there are some motherboards that only offer x16/x8/x1 with the 28 lane cpu's. 4) x299 chipset will now offer pcie gen 3.0, where as x99 only offered gen 2.0. this allows for the m.2 ssd's to run off the chipset, rather than use up valuable or limited cpu pcie lanes. 5) optane memory - right now optane is only offered as a cache solution. this will be targeting cheap off-the-shelf computers that only come with a hdd. for any computer using a ssd(s) it will serve no purpose and shouldn't be an issue for builds here. 6) kaby lake X - this is perhaps the most confusing part of x299, a so called "high end desktop platform" offering 4c/4t and 4c/8t cpu's. these kaby lake X cpu's will also have the intel graphics disabled, still only offer dual channel memory support, and only 16 pcie lanes. intel claims these cpu's are for upgrade path options, but with motherboards costing so much to enter x299 it doesn't make sense. anyone dealing with a budget that tight should be using amd ryzen and not wasting money on an expensive motherboard with features they can't use. some people, myself included, think this is intel attempting to make another change to their chipset platform and restrict overclocking to the HEDT (x299). if that's true we might see unlocked cpu's only offered on x299 and removed from the next main stream release of coffee lake, or perhaps the next main stream platform after that if intel wants to do this more gradually. 7) motherboard raid has some big changes - intel has added support for m.2 motherboard raid, but appears they have some limitations. the news stories say motherboard raid will only support m.2 raid-0 for free, and other levels of m.2 raid will require a hardware key to unlock. worse yet, the news stories also report that motherboard raid will only work with intel ssd's. if this is true its a very very anti-consumer move by intel to lock down their platform and force users into purchasing intel m.2 ssd's and expensive hardware keys. for most builds here we won't need raid m.2's, and if someone does they might be fine using windows raid instead. 8) prices - some big price drops, but only at the 8 core cpu and up. while the 8 core cpu got a decent price drop, it also got the pcie lane count dropped from 40 with last gen cpu's, to 28 lanes. while these price drops will be welcome, and a direct response to amd's offerings, intel seems to be cutting corners with pcie lanes and thermal paste, and trying to make up for lost money by trying to force folks into buying intel ssd's and raid hardware keys. with intel building walled gardens and charging 2x the price of amd cpu's, some people are calling intel the new apple.
