Currently I have an i5 4690 non-k processor in my build with a gtx 1070. I am looking to upgrade my cpu to something better. After some research I found that a i5 6500, a gigabyte h110 mobo, and 16gb of ram came to about $330. I also found that the i7 4790 was only $305, which means I do not have to upgrade anything else. Which should I choose?
