The FX 8370 will be coming out for slightly cheaper then the i7 4770k (in the 3770k's range). It is only 300 mhz lower at stock speeds but will be just as great of an overclocker with sufficient cooling.
Comparing a STOCK 8370 at 4.4/4.7 Ghz against a STOCK 3960x at 3.3/3.9 Ghz, in real world gaming at 1600p/1080p resolutions, the chips will prove to be equivalent, with a slight favor with AMD. (Given the 4.4 Ghz 3960x vs 5 Ghz 9590 tests here) This is a feat in itself. Just look at the difference in power consumption between the 9590 @ 5 ghz and a bulldozer FX 8150 @ 4.8 (8150 : 586W , 9590 : 317W) and Steamroller will continue this trend.http://www.bit-tech.net/hardware/2012/11/06/amd-fx-8350-review/7
Unlike the FX 8350 , the 8590/8370 will more than likely guarantee a 5ghz stable overclock with even a proper air solution. The FX 8350 sometimes even hit just 4.4 Ghz in reviews. Someone using a phase change should get their hands on one of these well binned chips.
"But, with very high frequency comes a high price. According to multiple reports, the FX-9370 and FX-9590 were initially listed by TigerDirect for $319 and $829 respectively. " CPUWORLD
