Pretty important since I use a 65" TV, but imo it's not about resolution vs. effects. The extra power in PS4 could be used for more / better effects, higher framerates, not just extra resolution - I mean with more compute units and higher throughput on PS4 you could have whole features or effects that make it onto the platform and not on the Bone.
And remember the underlying architecture is very similar between the two consoles, so the idea that Xbone will one day equalize the PS4 is misguided. It's like wishing that one day a 150HP car will be just as fast as a 200HP car. Never going to happen.
