If you are just looking for a gaming/all around rig, this would do pretty well at 1080p with med/high settings most games.

I like BadActor's suggestion, however, I think the i5-6500 is unnecessary paired with the GTX 960. Instead, why not go down to an i3-6300 and use the $50 you save on an SSD - the Samsung 850 EVO is the most recommended.
