Looking for help with this build before I go buying any parts (the part list is included below). I put the part list into PCPartPicker and it gave me the following error: "Some Intel Z170 chipset motherboards may need a BIOS update prior to using Kaby Lake-S CPUs. Upgrading the BIOS may require a different CPU that is supported by older BIOS revisions." I was hoping someone could explain what this means in layman's terms, along with helping to check my build for any additional problems. Keep in mind that I am trying to keep the build under $1500, but definitely still want a good build for intensive games that may come out in the future.
