My current motherboard is a Gigabyte H270 board and my CPU is a i5-7600k. I was thinking about maybe upgrading my MOBO to a Z270 board that I could use to overclock my CPU, but there aren't very many Z270 boards on the market and in my price range. Is it worth upgrading my MOBO now or should I wait and save up for a better CPU, MOBO, and a liquid cooler?
