What is the best processor of PC?

Hi, It actually depends on your needs, if you are basic user, who uses computer for checking emails and browsing, then you probably require a basic processor( Such as Intel3 Ghz or above or any Amd ), If you are gamer who likes playing high end games, then you probably need a higher Dual core of Quad core processes such as i5, i7 etc. or (AMD latest)..

i5 or i7

its depend on your requirement.  which type of application you want to run as per that requirement we decide which processor you should use
