In that case a common idiom is to "decorate"


decorated = [(obj.x, obj) for obj in objects]
max_decorated = max(decorated)
max_obj = max_decorated[-1]


Or to run through it "old style"

max_obj = objects[0]
for obj in objects:
     if obj.x > max_obj.x:
         max_obj = obj


Readbility is about the same I think. Testing should tell you which is 
faster in your case.
