Frame rates are more important to me than PP effects and crazy resolutions. Games that look good but run like shit are meaningless. Interaction and living environments are more of a priority for me though, not much has happened in the last decade or so and no one seems to be really trying to improve this. Not to mention AI, it's high time that AI got a serious upgrade, most developers still rely on purely mechanical adjustments for difficulty. So I suppose my answer to the OP's question would be; a bit but less than certain other factors. I still like to be dazzled though, I remember being amazed at Uncharted 4 on my new TV, gorgeous level design and environments and fantastic lighting with HDR enabled.
