Hi Xguy, I request you to register and then ask question, that way you will enjoy better at this place.

Coming to your question, it is very easy, from all three, Nokia 520 has best hardware for gaming but above that I suggest you to instead go for Nokia 525 , its even better, comes with Adreno 305 GPU and 1 GB RAM, you can play almost all available game on this phone without any problem.
