I recently started playing some games on my phone that require 3d rendering. Pretty sure it would struggle on an older phone. The 4GB of RAM I have feels slightly insufficient since the game gets closed by the OS if I switch to another resource intensive enough app. I'm not going to say you should pay $1000 for a phone, but just because you have no issues with a $120 phone doesn't mean no-one does.
