Who said people hate the i3? The 4th generation i3 CPUs are widely recommended for budget builds (at least on this site), I would even say that they're more popular than the AMD FX-6300.
I've been reading PC forums almost daily for a year now and never heard anyone say they hate the I3, or even dislike it. For a dual core CPU (with hyperthreading) it performs very well. It's just the I5 quad core is better for gaming.
