It is the general question of all the gamers while choosing an appropriate Ram capacity for their computers. However, it depends majorly upon the type of games you play. Some computer games would run fine with 4GB only, while others require 16GB or even more. Having 4GB or lesser varieties will limit your gaming without a doubt. 8GB would run just fine, but if you want to prove yourself and the system, you must go for 16GB or more. The components vary based on memory requirements like 1GB, 2GB, 4GB, 8GB and 16GB.
