Approximate numbers please. Not that I'm questioning you, I'm just want to know for myself. Like I said before, the days of Dolphin on Nehalem were before my time on the forums. By the time I made my first thread here, the 2500K and SB in general had been proven kings, but I never saw anyone talking about the boost in plain numbers (I assume I was just that late) though nowadays we talk about generational boosts constantly.
