Lifespan? I built this rig I'm using now in February 2009. There's still so few machines I could build that would be faster I haven't bothered. This is why I'm desperate to get my hands on LGA2011. Not because I need it, but because I've not had my rig building fix for over 2 years. X58 was too expensive for mainstream.. hence SB.. that's the main reason they did that. I agree that the 1156, 1155 thing was a little annoying, but overall, this X58 rig has been the longest lasting rig I've ever had in over 20 years of computing. It can still hold it's own against anything anyone in this thread could throw at it. So yeah... it's annoying that intel release new sockets, but they mainly do that for the mainstream retail crowd. The length of time between high end enthusiast sockets is much longer. IMO you should always go for the high end chipsets. They are replaced less often, and you won't really need to replace the CPU anyway. Realistically, how much would I gain if I replaced this i7 920 with a 6 core Gulftown chip? Certainly not enough to warrant the cost, that's for sure, but if I wanted to squeeze some more life from this rig, I could wait for LGA2011 to be released, and then grab a gulftown at a knock down price.. making last even longer. All in all.. stay away from the consumer products and you always have had long life in intel sockets. Besides, I don't think it's a fair accusation, when we had 775 which lasted from 2004 until pretty much now. LGA1366 was launched in 2008 and is still the most powerful platform for high end PCs. What do you want, architecture to have a 10 year lifespan? How would we make progress then? Like I said.. avoid the consumer/mid range architecture and go high end.. you'll get far more use and value for money long term. This is why 2011 gets my vote, and why I think it's worth paying a premium for high end motherboards and CPUs. Just my 2p.
