@ bamato in general principle I agree with what has been repleid to you. There is a "but" in there though because I know some real people who upgraded from the EVO and the PRO version of that motherboard to the Sabertooth 990FX and the CHV and both were then able *with* good cooling to overclock their FX processors beyond their previous 4.6Ghz-ish to over 5.0Ghz for benching. They were unable to do such with their original EVO and PRO version boards. If I remember correctly they were able to move their 24/7 clock upward a couple of 100Mhz as well and remain stable. Been awhile since they all upgraded so I don't remember the complete background.
But the *but* is that if you have very good water-cooling, then the CHV would then allow more cpu speed with stability. With just air cooling, I doubt you would notice a great difference as has been said already.
