If this will do 4000mhz 24/7 @100% load with good air or water cooling it's a winner in my book. I know some of you want much higher speeds for benching,etc but there just may be the reality that for that kind of use the yorkies or wolfdales may be the better choice.
I mean take a look at what people are doing with the E8600 E0's..
6500mhz and SP1m times under 7 seconds..
I don't think this one is going to be equal in those areas but will rule in others.
That's just what I think, not what I know..
