I can recommend the i5 4460 which is about ~$180. It's a locked 4690k for about $60 less but honestly is able to play even the most demanding games on Ultra settings (Witcher 3 / GTA 5) if pared with a good GPU. I would advise picking up a Z97 Motherboard to go with it so if you do want to upgrade the processor in a few years you have a path to the higher end of the Haswell line.
