It's easy when reading around to fall under the impression that an i5, at some point, won't be able to do something or run something as its lacks HT.
Obviously this isn't the case. The 3570K is a very powerful quad core processor and just as "future proof". All software has to be able run on it, and all the processors that came before it, and all AMD chips.
The logic is there on the chip just disabled by Intel to make an i5 - only they know why. Oh yes it's so they can make people pay 50% more for an i7!
The K processors, both i5 and i7, lack some obsure features (hopefully we'll never need) that Intel choose to leave enabled in the other models (the cheaper ones!). We're OK with this though.
