For gamers it's not the CPU that matters so far. For example you've read the following.

"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. ",3106-4.html

So without knowing why this is attractive, if this is for a gamer, look around for a higher GPU and maybe the i5.
