1. you do need a quad core
2. No phone can fully utilize a quad core.
3. samsung has always been a marketing gimmick, brandishing themselves as the best ,iphone killer, fastest phone when all they do is just squeeze in with more cores ,more this and that.

and FFS PLEASE LEARN ABOUT PROCESSOR ARCHITECTURE BEFORE COMMENTING, ITS SO ANNOYING WHEN SOMEONE CLAIM A QUAD CORE PHONE IS AS THE SIMILAR SPEED AS A QUAD CORE COMPUTER. THE SHEER STUPIDITY OF SOME GROUP OF PEOPLE IS UNBELIEVABLE!!!

Its funny of how u can just add a few numbers and wordings like super! instead of the current give name like "amoled" and people will start flocking like sheeps to buy.
