depending on your budget, I would recommend nothing below the FX-6300, and urge you to get the 8350 although its expensive or the 8320, and get a aftermarket cooler like the CM Hyper 212 Evo or better if you can afford. The 8350 your most future proof option, its also has the best value and price: performance ratio. it also overclocks good, as long as you have a good cooler. I personally have a 8350.
