As per the article, i5 has the on-die PCIe controller; Where as the i7 doesn't. Are there any significant performance issues or changes that would make one processor a better fit for someone or vice versa?

For a single GPU, there is basically no difference in performance.
For Multi-GPU, there is a bigger difference when using very high-end cards but this difference, from my estimation, is not large. At most I'd say 10%, but this is just a guess. I'm still waiting to see a review on the i5s x8/x8 configuration compared to i7-X58's x16/x16 configuration when using high end cards.

Which is better for Multi-GPU? You never say whether the difference comes from the on-die controller or if it is better or worse. Form what I gathered from the anandtech article, the higher bandwidth the i7 boasts from not PCIe on-die controller would serve better for a multi-gpu setup.
Would the on-die controller give quicker access times over the higher bandwidth of the i7 though? Would higher bandwidth or faster access speeds (if thats what the PCIe controller actually does) would make a more realistic performance change?
