I have a similar desktop with a standing desk that can go quite low + good gaming/office chair that I have approximately at desk height. My monitor is on an arm so it's a bit more than an arm's length away from me and at eye level. I have my feet on the table and the keyboard (made out of one piece with a hand rest) in my lap. Can't say exactly about productivity, but I really enjoy working this way.
