I just got an Intel Core i5-8600K CPU which didn't fit my motherboard at the moment. My computer is a - Lenovo H50 Tower PC (AMD A10-7800 3.9 GHz, AMD Radeon R7 240 2 GB Graphics, 12 GB DDR3 RAM, 2 TB HDD, DVD-RW, with a new graphics card installed. I'm wondering what motherboard would fit my CPU and the chassis to my computer which isn't the biggest. Any suggestions on what kind of motherboard I should by?
