This stared as an $800-900 'budget' build back in November of 2014... and here we are!
I originally bought the Asus 280X with an NZXT Source 210 windowed case. I also got 3 of Corsair's Air Flow Quiet Edition fans and the Cooler Master Hyper TX3 CPU Cooler. That setup was a little too loud for me so I decided to buy Fractals' Define R5 case, and the Noctua NH-D14 CPU Cooler. Some where down the line I wanted to see what all the hype was about with these SSD's. I ultimately decided to go with the 120GB Samsung 850 EVO. I went with the 120GB because the SSD is just being used for my OS and a few of the main games a play/stream. I planned to do a full Noctua build and get their new fans that they revealed at Computex but got impatient and started hearing really positive things about the Fractal Venturi fans and decided to go for a black/gray/gunmetal look. I plan to paint the gold mobo heatsinks and the red on the 390. I am very happy with the Venturi fans, they are whisper quiet. I have them set at such a low rpm that I sometimes I have to manually spin the fan to get it going.
I was starting to have issues with my 280X so I decided to get the 390. Unfortunately the DH-14 was too big and caused a clearance issue with the 390. The issue is more related to me have an H series motherboard, rather than the DH-14 being large. I was going to buy a Hyper 212 Evo CPU Cooler, but found the H100i GTX on sale so decided to go with that. Why not water cool the Xeon! I got the Xeon so I could game and stream to Twitch. The Xeon works great, although I could really benefit from the higher clock speeds of a 4790k, for example. I find myself turning down graphics settings in-game, or I'm turning down my x264 CPU preset in OBS because it's hard to maintain 60fps while streaming/gaming. This only applies to CPU heavy games though.
Picture 17: Idle temps. My CPU temps fluctuate because of my room temp. I've seen it go down to 19c, but that's a little too cold for my gaming comfort.
Picture 18: Temps after 2 hours of Crysis 3. The 390 got up to 72c. It would have gotten much hotter but I always run Vsync, and the fans ramped up to 1800rpm to keep it around 72-75c.

Update: 11/23/2015 - I added a picture of my setup and included the prices of the gear I use to stream and other custom parts.
I am also including a post I did on reddit that shows off some benchmarks I took - https://www.reddit.com/r/Amd/comments/3n1pzw/results_from_my_msi_390_ingame_benchmarks/
