What's interesting looking at all these scores is this: It's really, really apparent how absolute CPU performance has moved really, really slowly in the past 5+ years. We've got 2600K/2700K posting scores that are right up there with 4790Ks all OC'd. We've got i7-970/Xeon 5600s posting scores within striking distance of 5820Ks (both 6-core parts that can be overclocked, both over clocked to similar speeds).
That's 5 years of development, and 10-20% to show for it.
On the other hand, there have been some nice single-thread improvements, but still very small compared to historical improvements once we hit the Nephalem/Sandybridge era.
Of course if we look at GPUs we see development continuing to make strides (barring a bit of a slowdown in the 28nm era that should finally be coming to an end in 2015 with a node-size reduction). And of course Mobo features have gotten better, and storage (solid state in particular) has made bounds.
On the low-end part side we see huuuuuuge performance/watt improvements however. It's pretty clear that this is what's captivated Intel over the last 4 generations of Core.
