- the 6700k is not really needed for gaming. you can save by tuning down to an i5-6600k, which will be just as good when gaming
- the PSU is a bit over the tops, but it's a quality unit and for that price you take the extra 200W (it's actually cheaper than the 650W right now). this would eventually allow you to get a second graphics card down the way if needed at some point
- going for 2133MHz and an i5-6600 (non k) and a nice H170 board for ~110$ or less would eventually allow you to get a GTX1080 but it's somewhat overkill if you're not playing at least @2k
