I started doing the Stronglifts 5x5 program in the first week of November 2011 and made rapid progress with squats. I started with 135x5 and worked up to 265x5 (can only do 2-3 sets of that max though, very rough) and a 315 1 rep max. My bench and overhead press increased at most 20-25 lbs. I don't really feel like I've made significant upper body strength gains doing the program.
My bench stalled out at 245x5 a couple weeks ago and has been hovering in between 235-245x5 since that time. Overhead press has been stuck at 125x5.
That didn't really bother me because I was making good gains with squats, but this week I feel like I've regressed on those.
Right now I'm at 290 BP, 315 squat, and 315x5 deadlift. I want to reach 350/450/500 as quickly as possible.
