The FX-8370 is though. They are all basically the same chips set to different clock speeds, so you could always overclock the FX-8370 to the FX 9590's speed "if" you have good enough cooling and a decent power supply to handle the load.
Ok Then..So lets say that i go for 8370, i buy a good water cooling system or create my own loop... and have decent temps and stable OC at 4.7ghz more or less...What is going to happen with the vrms? i need a good solution for this...also to mention that money is not a problem
