Since no prices were given I think you would use to get benchmarks on the GPUs and pick the winner.

However I still like this now under 1K Haswell build.

The CPU is rarely the bottleneck in games. I'm sure you've read this:
"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
