Here's a note about that and gaming.

"Our tests demonstrate fairly little difference between a $225 LGA 1155 Core i5-2500K and a $1000 LGA 2011 Core i7-3960X, even when three-way graphics card configurations are involved. It turns out that memory bandwidth and PCIe throughput don't hold back the performance of existing Sandy Bridge-based machines. "

It seems the general public has been successfully brainwaxed that the i7 is always the better choice.

We have a 1080 display on a laptop. Nice but I went back to a lower count on my next laptop.
