Help me pick parts for my first gaming PC?

For Intel Haswell:
Go with DDR3-2133 or 2400 if you'll play Fallout 4, GTA V, Far Cry Primal, Assassin's Creed Syndicate or any other similar modern open-world game. They use high speed RAM very effectively and grand you an additional ~10 fps suprisingly. So obviously it is worth it. You need a Z97 board for DDR3-1600+, so It's recommended over H97. I'd pair it with the 4690k.

However can you not afford Skylake? i5-6400 + ASRock B150 Gaming Hyper will let you OC both the CPU and memory.

Difference isnt major, but you cant overclock the 4460, you can overclock the 4690k.
If your motherboard only takes 1600, if wont accept 1866 the ram will run at 1600
The motherboard I list below served me well for a long time, until I updated BIOS and had to RMA it, but that was my fault.

For a single GPU setup, the Skylake list with the i5-6400 is much better value.

If you grab the 6400 and B150 Gaming Hyper you can overclock it whenever you wish to plus you save money compared to an i5-4690k build. I'd grab the B150 Gaming Hyper as it will run your RAM at higher speeds. These higher speeds prove to make a difference in open world games.

Ofcourse, all you need for the modern games is a good i5. The Skylake one has faster cores than all the previous ones too so you should be blazing depending on the GPU you'll pair it with.

I've got an i5 4440/R9 390X rig and it runs games great with 16GB of 1600Mhz RAM on an H97 motherboard; you'd get far more out of a better GPU than CPU or RAM speed here.

I have another rig running a 4770K/390X and the differences are negligible as far as CPU is concerned for the vast majority of games; like 1-5 FPS on average, with the exception of Rome 2 on Max settings where the 4770K pulled 46FPS vs the 29FPS of the 4440, but not that big a deal in that kind of game imo. Shadow of Mordor performance was exactly the same between the two, same for Attila Total War. In Dying Light and Shogun 2 the 4440 actually squeaked ahead of the 4770K by a couple of FPS. If I had to choose budget wise between a 4690K or a 4460 vs a better GPU, I would get a better GPU. The difference here between a lowly 4570S and a 4690K equipped with the same GPU is so negligible as to not be noticeable in game http://www.anandtech.com/bench/product/1368?vs=1261. As to FO4 with my 4440/390X I get 40-50FPS @3200x1800 VSR with a mix of ultra/high and draw distances maxed, good enough for me. If you can bump up to a 390/390X I would do that. That being said the i5 6500 should be plenty and a hair cheaper than haswell/refresh at this point; keep in mind that I only buy from amazon and newegg myself as I've had very good experiences with both. with that in mind here are the options I would recommend taking into consideration what you listed as bought and adding the Operating system:

Option 1 with R9 380:

don't be fooled by the overclocking bits, in action it hardly makes a difference (if you want to do it for fun then that's a different story), see here for the ancient Bloomfield i7 965 @3.65Ghz keeping pace with a 6700K @4.7Ghz http://www.maximumpc.com/bloomfield-takes-on-skylake/#page-2 ; note also that the Skylake systems here are running DDR4 3000 and the i7 965 is still nipping at their heels with its DDR3 1333Mhz RAM in a demanding open world game, The Witcher 3.

on your build swap out the cx power supply it not a good unit. look at toms hardware power supply tier list get one on the tier one/tier two list. spend some money replace the intel stock cooler if your going to game. the h7 or any good air cooler that fit in your case will work better then the stock intel one. wait on buying the gpu next week 5-6 nvidia doing there pascal gpu launch.
