is there a reason u went with intel processor? (nothing wrong with it just curious). I have a very similar build but with an AMD fx-8350 processor, 16Gb g.Skillz Ares ram 1866, 1Tb hybrid drive, and an asus gtx 780. its destroyed every game ive thrown at it and temperature wise gpu hasnt hit 55oC adn my cpu hasnt hit 30oc (im using a corsair h100i water cooler)
There is pretty much nothing wrong with what you have. If you are going to microcenter for your 4770k I would get one of their cpu motherboard combos and save some money. I believe they have a gigabyte ud4h in the deals. If yo are just gaming you could also step down to a 4670k but that is up to you 80 dollars isn't a terrible expense. I would ditch the psu for a seasonic 760w platinum from newegg. They have a 35.00 promo plus a 20.00 mail in rebate.
You also have no cpu cooler. You have a K processor and a OC motherboard so I assume you want it overclock.
Noctua nh-u14s
noctua nh-d14
phanteks tc14pe if you like colors
coolermaster glacier 240L
swiftech h220
Those are some of the coolers I recommend.
The corsair h100 as well as the offerings from thermaltake and nzxt aren't bad. They work and they are cheaper but not as nice
on the water cooling topic. pay attention to what fits your case. some of the rads are thicker then others. see if your case might of been designed for one of the companies water coolers (if they make them). I have an corsair h100i (i love it my cpu hasnt hit 30oC ever but my case was designed with it in mind (corsair carbide 500r white)
