Hexus posted a review on the Gigabyte Aorus Z370 Gaming 7
A quote from the article:
Ready and primed for that premium Core i7 8th Gen build. Gigabyte/Aorus is coming loaded to the Intel 8th Gen Core and Z370 party with at least nine motherboards from the get go. This new Intel platform offers mainstream users six cores and 12 threads from a couple of Core i7 processors, but the salient point for companies such as Aorus is that these new chips require the Z370 motherboard - older boards simply won't work with the new CPU mojo.Gigabyte Aorus Z370 Gaming 7 Review @ Hexus
This is why Z370 is construed as a big deal, and the company's stack runs from the Z370-HD3 through to, at the top end for now, the Z370 Aorus Gaming 7. We are in an ideal situation to evaluate the relative merits of the Gaming 7 because we have recently reviewed the X299 and X399 variants.
