I don't think it was really need, just a perfectly reason question. That is, if I was to replace my aging system now, do I go for Ivy Bridge, or does the imminent Haswell processor have sufficient advantage that makes it worthwhile holding on for a few months more and adopting that?
In the past it was a very pertinent question, espescially for PC enthusiasts, gamers, or anyone who would be using their processor to the full rather than just for everyday useages like browsing.
However, I think it;s much less important given the way that Intel in particular has shifted it's focus away from making improvements in processing power and towards making it's CPU's more power efficient and having more capable onboard GPU.
This is very clearly because Intel reads the consumer market as being driven more by the needs of mobile devices, which have to be cool, power efficient and have sufficient built-in graphics, than it is by any demand for sheer compute power. I think it is safe to say that the processor power requirements of almost any home user with an exceptional few, can easily be met with the current range of processors. You simply do not need anything above what a core i7 can provide (although one assumes, it is always possible to say that transcoding a large HD video file faster would be nice!)
Haswell will offer improvements in processor power, but not great strides. If you are wanting to exchange an old system for a new one then there is no pressing need to wait for Haswell.
On the other hand, there is also no pressing need to jump for Ivy Bridge if you are content to wait that little bit longer. Haswell will deliver more 'bang per buck', just not a lot more. And improvements in things like power consumption and onboard graphics do make it that little bit more desireable.
I think if I were on the point of deciding to make a major upgrade then I would wait for Haswell. But if my system were giving me real problems or I spotted a special offer, I would have no issue with deciding to just go for Ivy Bridge.
There is certainly not going to be a situation where you are going to go for Ivy Bridge and then find you could have got something twice as good for the same money just by waiting a few months and getting Haswell instead.
I think the days when processor releases marked big jumps in capability are gone. It's all about making processors more suited to mobile devices than making desktops number crunch quicker now.
