Its an oc's forum so yeah single monitor gaming to me is bog standard not high end.
I think the op wants a 1080 setup. OC'ed sany/ivy/haswell all do the job. Spend money saved on gpu 120hz monitor etc.
I will always choose Intel/Nvidia over AMD - had one rig from them and was disappointed (sold it after few months).
