whats considered a good gpm in lol

I've played yorick and in 2 games in a row, I got crazy fed off of just splitpushing. Once I'm done with both top and bottom, I just become a good resource for the team. Anyways in both games, I had an insane amount of cs and I had a gpm of 500. Gpm for those of you who don't know means gold per minute. In DotA, if you have a 1k gpm, you basically are going to win no matter what unless you start inting. Also some of the safelanners which are basically the adc's will actually kind of triangle farm. They will farm the small camp,the medium camp then clear the creep wave. That's how they get so much farm but it doesn't mean they get 1k gpm. It just boosts gold. what I want to know is what's considered a high gpm in lol. Also for those of you who say farm doesn't matter and kills win games, you have never been more wrong in your life. It's objectives. Also those 2 yorick games ended around the 30 minute mark. Anyways what's considered a high gpm.
