$500 gaming build

Is there another cpu that is close to the i3 but quad core. Several of games I want to play require a quad core cpu. Or can the i3 act as a quad-core? Thanks
 
What games do you want to play? The i3 has two dedicated cores but with the help of Hyper-threading they support four threads.
