I game on a 60Hz monitor and i do not like anything more than 60FPS i tried 120and 144 but idid not like it, call me weird but its my preference lol. I know i will need a new Motherboard and i would get the GIGABYTE G1 Gaming GA-Z170X-Gaming 7 and i guess a set of G.Skill 4x4GB DDR4 memory and i do not know what speed of memory to get because i do not know much but as long ass its faster than 1500MHz of what my DDR3 memory is now. But back to the topic, will upgrading to the i7-6700K be a huge performance gain when comparing to my i5-4690 i am using now?
