In multithread heavy workloads that utilize more cores, the 8 core FX has the advantage here. The reason why i5s are recommended over FXs is because Intel's single core performance/single threaded largely dominates AMDs. Because of this, alot of games still rely on more single threaded power and thus giving better FPS to i5s. That's the reason why even everyone recommends i5s over FXs. The FX-8370 is the same as a 8350 but with maybe 1~% more performance. It's clock speed is 100Mhz more than the 8350.
