To be honest i3 4130 is not a bad little dual core. Its advantage is having hyper threading which makes the pc see it as a quad core. Also not many games will utilize more than 4 cores and I am sure OkAM will be no different. Thing that has me is 16gb ram lol, even the most demanding games i.e Crysis, Far cry, Gta 5 dont require 16gb ram, 8 at the most. That is good that you can play it with decent fps.
