I like my i7 9xx systems and have no intention of getting rid of them for a few years yet.
As to performance sometimes they surprise me, the other week I tried running some ultra fast memory on my i7 980 to see how high I could go. The system was 100% stable @2300mhz plus running 9-11-11-25 1T. This is not bad for a CPU with an IMC rated for 1066mhz and a mobo rated for 2200mhz max. I don't think any of the standard sandy bridge CPUs can manage that.
Isnt that the whole bonus with x58 and x79? More of everything in terms of raw output? I was kinda hoping to be able to stick to an X chip when haswell gets here, like x90 or whatever they might call them, if they are going to make one.
I just found this interesting
review/benchmark . Its shows a stock i920 in various tests vs 3930k and others. In games the i7 920 is either just as fast or incase of the WoW(loves cpu power) test 20% slower on stock vs an overclocked 3930k. Im stunned really. Im running a roughly 42% overclock so in theory I should match that 3930k pretty darn close. Guess you peeps were right afterall.
Im seriously surprised that a 380 dollar chip can follow one twice as expensive and are maybe even be better(?) at clock for clock with the exception of (in the review) highly threaded physics
