Considering the GPU is inside the CPU itself and not part of the motherboard, performance should be almost identical. Regardless of which board you use, you're still using the same Intel 2000 or 3000 embedded within the CPU itself. Though, it's kinda pointless to choose a K-series CPU for the 3000 GPU on an H67 board because you won't be able to overclock it. That's the K-series main enthusiast selling point - overclocking.
