I have 700x32s and I pumped them to 90psi for my test drive around my neighborhood and they felt great. Today I took a ride that is part of my work commute that took me over some chip seal and other rough surfaces, and it was harsh at times. Of course, I just switched some from 26x1.95s that I ran around 55, so it's not surprising I noticed a difference. I think I'm going to drop the pressure some but I don't want to go far enough to bring pinch flats into play.
