I think it is a great CPU for only a little bit more than the i5 4690k. You get pretty much i7 performance for $60 less. Here would be the one I would go with.
I have wanted a 1231v3 for quite some time. Just haven't had the money. I live close enough to Microcenter, that I can get a 4790k and motherboard, for about the same cost, though.
