I'm sure there are a few enthusiasts that might like to play around with VT-d, but that isn't what the technology was developed for.
And yes, Sandy Bridge-E is a totally different beast. Every processor can be overclocked on that platform due to the way the platform is designed. That doesn't mean everyone overclocks that use it.
And don't confuse the Extreme edition processor with K series processors. The Extreme Edition processor offer more than just an unlocked multiplier. Professionals do use those processors and don't overclock them. There is no locked equivalent to the 3970X, it is just a flat out bad ass processor. However, there are locked equivalents to the K series processors. There is a 3770 that matches the 3770K, the K is unlocked and the non-K has VT-d.

Perhaps you misunderstood what I was trying to say with respect to your earlier post newtekie1.
I was only pointing out that the LGA2011 platform has processors that can OC and have VT-d (3970X, 3960X, 3930K and 3820). The “K” nomenclature is peppered in there as you know. As far as I know all the Sandy Brdige-E processors C2 stepping and above have functional VT-d support in hardware with OC support and that includes the Core i7 3930
K.
There aren’t that many “K” processors to begin with. Considering only the most current processor line available (Ivy Bridge and Sandy Bridge-E) the percentage of K processors that support VT-d is 33.3% or 1/3 (out of the 3930K, 3770K and 3570K). If you consider OCable processors as a metric all the Sandy Bridge-E processors can OC so the percentage there (with Ivy Bridge) with respect to VT-d support would be 60% with VT-d support.
The value of OC + VT-d is up to the individual. I agree that most people who want one of these features doesn’t necessarily care about the other.
