Honestly there isn't a set number of calories before it's wasted. It is possible to take in more than you can process, but your own metabolism and body will effect that. It's just kind of trial and error til you find the point of diminishing returns on your calorie intake.
That said, unless you're a competitive eater you probably aren't going to have the capacity to hit those caps for a while. I wouldn't worry about it too much unless you're going hard on the gainer shakes.
