Please bear in mind Intel does not sale directly, I would recommend waiting for any community member that may provide details about this matter.
For Intel processor information go here: Intel: Shop for Tablets, 2-in-1s, Laptops, Desktops, Smartphones, Servers
The processor that you have is quite new, so the motherboard availability is limited however we may expect in the future to see more motherboard options for that CPU. As a recommendation you can keep the following link where we will add motherboards that are supported by that processor (as of today there are only 3 compatible): Compatible Motherboards
The good thing is the chipset support (Z87 and Z97. You can see that on this link: ARK | Intel® Core™ i7-5775C Processor (6M Cache, up to 3.70 GHz)) so that is why we may expect more variety in the future for that processor.
If you have more questions please let us know.
