So far, only a few details have been disclosed regarding Intel's 8-series motherboards, and even fewer details have been revealed about the specifics from each manufacturer. What has been learned now is that ASRock's upcoming Z87-Extreme4 motherboard is the first to get Windows 8 certification.
While for most of us it won't make a difference whether a motherboard is certified or not, it is important that the manufacturer had enough faith in the product to let Microsoft test it under a specific operating system, and that if granted the certificate, it is fully compatible.
The report also shows a small detail about an upcoming Haswell CPU. A close look reveals that the testing was done on a machine that was running an Intel Core i5 processor that runs at 3.40 GHz. Since this is a Z87 board, it is in all likelihood a Haswell CPU.
