asus rog g20cb

Hi guys, First post on here. I bought a new ASUS ROG G20CB-DB71-GTX1070 with a i7-6700K 3.4Ghz CPU. I am having some bottenecking emulators and I'd like to upgrade the CPU. I have upgraded the BIOS from build date 2016 to the current one built in 2018 - version 2202. I've read on forums here...
