Way too much in my opinion. If you are going to do a full-body workout 3 times a week this is overkill. The whole point of a 5x5 program is to stick with a handful of big exercises and push them hard while cutting out the fluff. I would recommend something like this:
A: back SQ 5x5, bench press 5x5, bent over row 5x5; optional abs and/or 1-2 sets of biceps or triceps
B: Front SQ 5x5, military press 5x5, DL work up to 1x5, pull-ups 3 sets to near failure; optional 1-2 sets of arm work
If your work hard with this set-up and try to add weight each workout or every other workout it will be plenty. Start with weights where it only takes a moderately hard effort to complete your sets and then add weight every workout or every other workout.
