Poor Performance with Brand New Hardware6

So I just built a new computer with the following specs: MSI Z170A SLI Plus Intel Core i5-7600k GIGABYTE GTX 1080 OC Edition 16GB DDR4 @ 2400MHz Rosewill Quark 550W Gaming Power Supply I’m using SSDs for OS and games I’m not new to building and I’ve done it all before, but this time around I seem to be having issues. I had to borrow a friend’s Skylake CPU to POST and update the BIOS to allow for the Kaby Lake i5.
