So I'm building my first gaming PC, and I'm thinking about purchasing either an i5 6500 or an i5 6600k. I've heard that purchasing an i5 6600k can be overclocked and the i5 6500 can't but I don't really want to overclock my CPU. What's another reason to purchase the 6600k over the 6500? I've been leaning towards the 6500 as it doesn't require purchasing a cooler and it's much more convenient for me as I already have a power supply that's perfect for the 6500. Any thoughts?
