    I think I would like to see some more real life comparisons before deciding. From what I've seen so far, it looks like unless you are using software that will take advantage of the 8 cores of the 7820, the 8700 would be the way to go. With it's overclocking ability, the speed can make up for a lot of deficiencies. The reason it is the better gaming CPU is mostly because of it's much higher frequency in apps that only use fewer cores.. But don't forget, the 8700K has 6 cores to do an adequate job on some multi threaded apps too.

    The Chipset is basically a remake of the Z270, which makes it a more mature chipset than the X299 and won't suffer some of the problems that will require bios updates to fix. Plus, at least from initial reports, the 8700 seems to run a lot cooler than the X299 CPUs do. The X299 chips by all reports are extremely hot, but some of the reviewrs were running stress tests at 4.8 and 5 Ghz on an AIO cooler. They got hot, but within tolerances. That would never happen on the X299 chips, if you could get them overclocked that high.

    Having said all of that, if you use software that takes advantage of 8 cores/ 16 threads, the 7820 is the way to go, if you do a lot of it. The 6 cores will do the same thing, it will just take a few minutes longer. That's just my take on what I've seen so far but I still want to see more reviews. I have a 6 core now and have seen little other than video encoding that would use all of the cores. If I could get it running as fast as all of them are overclocking the 8700K, I wouldn't be thinking of upgrading. Just my 2 cents.

    The 8550U is a true quad core. I also ordered a 256GB SSD and 16GB of RAM for her.

    Intel Core™ i7-8550U Processor (8M Cache, up to 4.00 GHz) Product Specifications
    Nice but what's the system specs? Curiosity

    And nice processor. Mine has the 7600U (duo core)

    Don't necessarily disagree here but this is always the case with new boards. That said, I'm of the mindset of always going with the newer/improved tech of the motherboard given the choice. However, where pure performance comes in, I may pause there. It really depends on what you intend to do with said system - pure performance or newer/improved tech. For me, since benches are no longer part of my build mindset I'll opt for the better tech given the choice. Obviously price will also be a major factor.

    That said, the i7-7820X is priced near $600 bucks, but what of the i7-8700K? And what of the performance difference between the two at the given price difference?

    Regardless, I wouldn't mind having either system so....

    One thing to also consider is that the Z370 motherboards appear to only support 2 memory channels of DDR4 so far while X299 supports 4 channels.

    And the 7820 does have more PCIe lanes.

    Have to admit I've not looked at either board (yet) so I'm at a disadvantage there. What's the max memory of either board?

    The motherboard specs will determine this more, but these are the specs for these two:

    Intel Core i7-7820X Processor (X299)
    i7-7820X - max 128GB RAM

    Intel Core i7-8700K Processor (Z370)
    i7-8700k - max 64GB RAM

    With 64GB being around $650 too these days for DDR4-3000
