Last rig I had was what I got for trading my Xbone. After doing research, I decided to build my own setup and was interested in the next step in resolution. I sold my old parts for about $600 and set off to building this.
Didn't have one issue with the actual build, it went really smooth. I didn't do a fresh install of Windows 8.1, I only had to download Network drivers on a thumb drive to get internet to work. i5-4690k was chosen because I only really game. i7 wasn't worth the extra $100. GTX970 runs flawless at 1440p regardless of the recent news of 3.5GB's of VRAM. A second one will be ordered once more advanced 1440p monitors come out. The Samsung 840 EVO is used for the OS and utilities. Intel SSD is for games I play most and the WD drive is mass storage.
The Phanteks Enthoo Pro is a fantastic case. I was coming from an NZXT Phantom 410 and even though it was a good case as well, it had no dust filters. I do not use a CD drive and was able to pull the 5 1/4 bays out, which is great for the cooler and airflow. Be careful though, I left my PC on overnight last week (I usually shut it down daily) and the stock 200mm front fan died. Replaced it with 2 Corsair white LED 140mm fans I had laying around.
