Well, I'm not convinced that is true. Yes, Haswell should double the FLOPs. However, at the same time, AMD and Nvidia are moving to 28nm which should also double the FLOPs. Knights Corner is a wildcard, but we know roughly where that will end up - around 1TFLOP/s, but the die area and power consumption is unclear.
I think the gap may narrow a bit, but you won't see CPUs catching GPUs soon.

GK110 will be plenty compute focused and reasonably attractive. It is good that they have a nice and efficient graphics variant though...while the margins are great for compute, the volume is clearly in discrete graphics.
