I use a Nokia Lumia 520 and lately I have been thinking about upgrading to the Lumia 525 as it has 1GB RAM. However what is stopping me that all the other features are similar to the 520. Is it advisable to upgrade to the 525 only due to games (although I do not play games on my phone much)? I want to know if the performance is better on the 525 compared to 520. Or should I wait for upcoming devices in future?
