Well I tested it and and 60fps theres no slowdown with over 9000 particles. I pushed it up to 50,000 and got a slight lag for a split second when they were created but then it ran at top speeds. This is just with my code. I'm sure with more optimized code you can easily push 70-80,000 particles.
The problem is I'm never going to need 80,000 particles. :/
