I'm building a super budget build around an i3-6100 that I bought for basically nothing ($13.46 ebay). I also bought the Asrock z170m pro4s mobo to hopefully over clock this and future 1151 socket processors. I'm looking for suggestions for the PERFECT match gpu from any generation or company. My goal is to be as close to zero bottle-necking between the CPU and GPU as possible and to minimize cost. Also, any suggestions will help as this is my first build: ram size, cases, coolers, upgrade paths, and whatnot.
