@Absolute I don't really care for CPU brand but I'd prefer to have something that will last 2 years or longer. So maybe the 8350 black edition or i5 4690k/6500/6600k.
Go with the Core i5-4590 if you want it at $200. 4690K selling for $239 ish currently. 8350 Is also ideal. The Skylake 6500 is almost the same price as 4590, as 6600K is slightly more expensive butwill require you to buy DDR4, which will push you towards the $300 budget if you decide to get 8GBs of it.
