CPU "requirements" in games are often only rough estimates. A game that requires an i3 4150 for instance will probably run well enough on an i3 3120. Be aware, as others have mentioned already, that none of AMD's existing CPUs are very good, either in absolute performance or in value. They're old, have no upgrade path, run hot, and have very poor per-thread performance which is important in most games. It's often the case that a $60 Pentium G4560 will match or beat AMD's 6 core and sometimes even 8 core CPUs, which are typically much more expensive, while drawing a fraction of the power and producing a fraction of the heat.
